Um... your supervisor asked for a seating chart. Everything's computerized-- software program. This here'll show you the number of people per table. 10 00:03:36,549 --> 00:03:54,567 Where were you during the crash? I was at the register, behind the bar. Did you see anything? A blurry Jaguar speeding through the intersection. ( car accelerating ) I thought the car would slow down, but it just kept right on coming, you know? I mean, if you ask me, that's the reason why old people don't belong behind the wheel. Yeah, I-I didn't ask you. Thanks for your time. 11 00:03:55,835 --> 00:04:25,632 I'm sorry. I got wrapped up in... Hank. Yeah. An old Jaguar with a GPS unit. That's strange. Yeah, not your granny's Oldsmobile. GRISSOM: We're cleared to go in? Yeah. Gas company shut off the valve at the street. Paramedics aired out the scene. STOKES: Homicide radioed in a D.B.? Vanessa Arnz. She's in the master bedroom, next to the son's room. GRISSOM: Thanks. 12 00:04:29,802 --> 00:04:41,581 The gas company spikes its natural gas with mercaptan-- smells like rotten eggs. I don't smell anything. GRISSOM: All's I smell is mothballs and stale tobacco. STOKES: Science geek. 13 00:04:43,049 --> 00:04:45,785 Takes one to know one, I guess. 14 00:04:51,591 --> 00:05:12,945 Hello, David. Hey. She's hot pink, like a maraschino. Makes our job easier. Death was not the result of natural gas inhalation. No, but carbon monoxide's still gas. Right, when carbon monoxide displaces oxygen in the blood, victim asphyxiates, turns... pink. 15 00:05:21,654 --> 00:05:29,562 Was Mr. Arnz in bed with her? Um, yeah. Paramedics said they found them both in here. So why is she dead and he's alive? 16 00:05:31,764 --> 00:05:43,109 You know, Dave, when I was a CSI-One, I would've tried to answer that, but now I know "where" before "why." First step, find the source of the C.O. I'll grab the Nighthawk, fire it up. 17 00:05:45,845 --> 00:05:52,752 Mr. Arnz has been stabilized. They're preparing him for transport. I want to take a look at him. Yeah. 18 00:05:53,886 --> 00:06:18,978 ( garbled radio transmission ) I wake up in the middle of the night sometimes, if I get cold. Vanessa steals the covers. Uh, I woke up and my head was spinning. I... I think I'm coming down with something. Then I look over at her... ( gasping ) Vanessa. ( clattering ) ( phone dialing ) Oh, my wife isn't breathing. Do you remember anything else? 19 00:06:19,812 --> 00:06:50,676 No, I don't remember hanging up the phone. I must've passed out. Next thing I know, the paramedics are taking me out. PARAMEDIC: We got to roll. Patient will be at Desert Palm. Wait a minute. What about my boy? Peter seems fine. Wait a minute. What about my boy? Peter seems fine. The kid's 18. Signed an AMA. ( garbled radio transmission ) ( vehicle engine starting ) Peter... my name's Gil Grissom. I'm with the Las Vegas Crime Lab. You want to ask me questions. 20 00:06:51,978 --> 00:07:00,119 I was in my bedroom, asleep. I heard the doorbell. It was the paramedics. A few minutes later, the police showed up. 21 00:07:02,555 --> 00:07:14,433 I'm very sorry about what happened to your mother. Why are you sorry? You're not responsible. You didn't know her. You don't know me. 22 00:07:19,906 --> 00:07:29,215 WOMAN ( over PA ): Technician to Radiology. Technician to Radiology. How's she doing? Doctors are working on her right now. Doesn't look good. 23 00:07:30,550 --> 00:07:37,456 Relative? Driver's been I.D.'d as Diane Lambert. That's her grandson Corey. 24 00:07:39,625 --> 00:08:53,532 Hi, Corey? Hey. I'm, uh, Sara Sidle. I'm with the Las Vegas Crime Lab. Do you mind if I ask you a couple questions? I don't even know why she was in Las Vegas. We live in Laughlin. She hates it here. Corey, um... did your grandmother own a Jaguar? Yeah... ( sniffles ) Yeah, she won it in the, uh, quarter slots. First two coins and bingo. Triple stars. She also win the GPS? No. She hadn't been driving it much. WOMAN: Yeah, I'm okay. Uh, she got lost a couple times, and it scared her, so, for her birthday last month, I bought her the unit. Can you excuse me for a second? Yeah. Can you excuse me for a second? Yeah. ( indistinct message over P.A., phone ringing ) Hey. Hey. And the EMT of the year award goes to... Not me. Death toll's now three. Could climb to four. Elaine-- the girl in the wheelchair-- she's one of the lucky ones. You were amazing. Eight years in the rig, first time I've actually been a part of the scene. I can't stop it going through my head. Yeah, you never know when your life's going to change. Listen, I-I-I... I got to get out of here. You need a lift? No, uh, I drove. 25 00:08:54,734 --> 00:08:57,270 Hank? 26 00:08:58,938 --> 00:09:04,010 I'm really glad you're okay. Thanks. 27 00:09:08,714 --> 00:09:42,882 ( garbled radio transmission ) Plenty of tire treads, but nothing looks fresh. So you going to tell me how it went? I got called in by Internal Affairs. How do you think it went? Too many questions. Thanks. I wish I could've pleaded the Fifth. Yeah, you don't answer their questions, you're looking at more days off without pay, and that blows. Yeah. It's a red light camera. Did any of the witnesses see the driver run the red light? Nobody mentioned it, but the camera's there. Big Brother knows. I'll put in a call. 28 00:09:43,816 --> 00:09:45,217 WILLOWS: Motor oil. 29 00:09:48,654 --> 00:09:57,163 Now, that looks fresh. ( car accelerating ) ( metallic clank ) Hitting the curb could've caused the car to buck. 30 00:10:02,935 --> 00:10:10,843 Traffic light, intersection, curb. Well, either the car wasn't working, or the driver wasn't. 31 00:10:19,151 --> 00:10:25,358 Looks like the newspaper dispenser used to be here. ( car accelerating ) ( metallic clank ) 32 00:10:29,829 --> 00:10:31,931 Catherine. 33 00:10:33,833 --> 00:10:41,874 Tire treads. That kills one theory. Car's brakes must've been working. She tried to stop, but it was too late. 34 00:10:45,878 --> 00:11:51,944 Let me guess: no air bags in the vehicle. No. Preliminary cause of death, epidural hematoma. No. Preliminary cause of death, epidural hematoma. Her head impacted the steering wheel. ( glass shattering, groaning ) Blood accumulated between the table of the skull and the dural membrane. Her injury is consistent with a severed middle meningeal artery. What about pre-impact? At the risk of feeding a stereotype, she was 72. Any indication of stroke, Alzheimer's, heart attack? I considered and dismissed all age-related factors. No arthritis, uh, no significant impairment of her senses. She has had part of her colon removed, probably due to injury or prior medical condition, but, Sara, it's irrelevant to your case. I found no physiological explanation for the crash. Well, that's a bummer, 'cause at this point, we got no forensic one, either. STOKES: Carbon monoxide fills the air when any carbon-based substance is ignited. ( detector beeps slowly ) Kid checks out, so... the point of ignition's probably this room. You know, the two most common causes for accidental household C.O. poisoning: unvented space heaters and improperly maintained chimneys. I don't see any heaters. 35 00:11:53,079 --> 00:12:06,492 My dad's a fireman. Last Christmas, he gave all the kids C.O. detectors. ( beeping faster ) Would've saved this woman's life. 25 parts per million. That's the highest reading in the room. 36 00:12:08,127 --> 00:12:15,401 This is a natural gas burning fireplace. Burns clean. C.O. fumes should be minimal at best. 37 00:12:22,041 --> 00:12:26,846 Foreign substance. Still warm. 38 00:12:29,882 --> 00:13:00,012 There was something other than natural gas burning in here. If the gas company hadn't shut off the gas, whatever that is probably would've burned up. Chimneys are designed to funnel smoke up and out. If this fireplace was the source of the C.O., the fumes should've traveled up the chimney instead of permeating the room. LOCKWOOD: Unless the chimney isn't doing its job. ( clanging ) The damper's busted. 39 00:13:01,313 --> 00:13:14,994 ( creaking ) ( wind whistling ) Foreign fuel source and a compromised chimney. I think we just ruled out accident. 40 00:13:16,328 --> 00:13:32,177 ( indistinct chatter ) Hey, I hear you're working on Hank's case. I believe it's my case. Territorial. You know, guys don't like that. You're crowding me, Greg. Well, I have some information that could bring us even closer. 41 00:13:33,145 --> 00:13:47,860 But you first. What are we looking at? I downloaded the memory from the GPS in the Jaguar. She wasn't a local; I wanted to see if she got lost. SANDERS: Well, did she? Diane Lambert lives in Laughlin. Excuse me. 42 00:13:50,930 --> 00:14:35,207 She took 95 North to Summerlin Parkway. Then she took Parkway to Rampart, made a left on Main Street and headed straight to Meadows Lane-- 16 North Meadows Lane. That's where she was going, and that's where she ended up. So does that thing tell you why? What do you have, Greg? Well, maybe she had the munchies. Tox screen came back. Mrs. Lambert tested positive for cannabis sativa. Grass? "Grass"? So '70s, man. Sticky green, the dank. The chronic, the cush, happy stick, wacky-tobaccy... Well, well, wait, wait, wait. Grandma was high? Yeah. Grandma was high. Yeah. Grandma was high. ( inhales ) As a kite. 43 00:14:36,041 --> 00:15:11,343 Hey. Return visit, huh? Hey. Return visit, huh? You're here about the tox screen. Yeah. Was Diane Lambert legally impaired? Less than two nanograms of THC, so, per NIDA, she wasn't. Oh. But, if she were a longtime user, her-her reaction time could've been slowed down, right? Uh, I know where you're going. Let me stop you. THC has no significant cumulative effect, so maybe the question you should be asking is: Why was a woman her age doping up? Okay, why was a woman her age doping up? Tell you what-- check out her optic nerve. 44 00:15:14,580 --> 00:15:47,346 SIDLE: Nerve's damaged. She had glaucoma. I thought you said she was in good health. That was before the tox screen came back. You know, it's not standard procedure to check for glaucoma, but the Mary Jane tipped me off. People think it slows the progression of the disease, but it just reduces the pressure in the eye and that reduction's only temporary. Prescription medications do a much better job. Unfortunately, they don't have the same side effects. Her vision could've been impaired by the glaucoma. It didn't affect her driving. Sara, Diane Lambert has nothing more to tell you. 45 00:15:49,581 --> 00:15:51,317 ( beeping ) 46 00:15:57,589 --> 00:17:00,786 Hello. Oh, hey. So, I got photos of the restaurant patrons off the DMV database and input the information per the restaurant seating chart and the police report. Who's Elaine Alcott? Who? Um, well, she was seated with Hank. I just thought maybe that... Oh. Anyway, uh... apparently, she told PD that she was returning from the ladies' room at the time of the impact. They must be friends. I saw him with her at the hospital. Okay. Um... okay, so, we've got 36 people in the restaurant. 12 worked for Sillmont Healthcare, a block away. Another ten were from the brokerage firm across the street, a couple of regulars, a few out-of-towners and... restaurant employees. Do you know how long it takes to get in touch with anybody at the Transportation Safety Bureau? It's way out of hand. Diane Lambert ran the light. 47 00:17:03,522 --> 00:17:26,478 WILLOWS: Wow. She sped through that intersection-- 52 miles per hour. That's more than twice the speed limit. BROWN: Well, the tread marks tell us that her brakes did work, so it must've been something else that malfunctioned, causing her to accelerate. Gas pedal could've gotten stuck, or... throttle plate could've jammed. There's only one way to find out. I'm on it. 48 00:17:55,507 --> 00:17:57,709 ♪ ♪ 49 00:18:08,287 --> 00:18:36,381 Hey. You have, uh... Ah, don't worry about it. How's it going? You find anything? No. Car checks out perfectly. Well, I did some more digging down at the TSB. I found out that the red light camera that photo'd our driver catches four times as many violators as any other camera in Vegas. Intersection's dangerous. Could be a death trap. 50 00:18:37,216 --> 00:18:43,155 MAN (over P.A.): CSI Burke, dial 991. CSI Burke, 991. 51 00:18:44,490 --> 00:18:49,228 I didn't page you.

Yeah... Hodges, that's what I think. Hmm. HODGES: Hey, boss. ( printer whirring ) Nice timing. 53 00:19:15,988 --> 00:19:33,939 Foreign substance in the fireplace is carbon. Associated minerals? None. Pure, unadulterated carbon. It may be pure, but it's not solid. Micro-pores. Sample's under the scope. ( throat clearing ) 54 00:19:40,312 --> 00:19:50,822 GRISSOM: Activated charcoal? Used in filtration systems, kitty litter, some medications... And possibly a murder. 55 00:19:56,395 --> 00:20:42,708 BROWN: Building has mirrored glass on it. Lets in the light, but keeps out the glare. Sun sets in the west behind us. Glare could be pretty intense in the afternoon. Could explain why this intersection is so dangerous. So you think the sun was a factor in the crash? Well, according to the accident report, the sun set at 5:30 yesterday. The accident was at 5:15, so the sun was still in the sky. Trees and buildings extend at least ten degrees above the western horizon. Yeah. All right, well, there's 24 hours in a day, 360 degrees in the Earth's rotation. 360 divided by 24 is... 15? 15. Sun moves about 15 degrees an hour. 56 00:20:59,057 --> 00:21:18,977 At 5:15 yesterday, the sun would've been about what-- 3.75 degrees above the horizon? Wow, you're fast. 3.75, huh? Then the sun was behind the trees at the time of the accident, so it was not a factor. Great. And our investigation is still in the dark. 57 00:21:20,679 --> 00:22:38,890 ( rock music blaring ) ( music stops ) I just got a page from James Watson. And I got one from Francis Crick. What's going on, Greg? Well, as you both know, Watson and Crick are the granddaddies of DNA. Without their discoveries, I'd have nothing to do all day. What have you been doing all day? A tox report on your d.b., Ms. Pretty in Pink. Uh, she died of carbon monoxide poisoning. Blood saturation level of 46.2%. No surprise there. Uh, nicotine levels are high-- she was a smoker. And she popped a couple of sleeping pills that night. Nothing probative. Well, what if I told you that Mr. Arnz had a carbon monoxide blood saturation level of 37%-- nearly ten percent lower than his wife. Mrs. Arnz was a smoker. Typically, a smoker's blood is already 10% saturated with C.O. STOKES: You mean smokers get a jump start on the poisoning process? Could explain the 10% difference. It could also explain why he lived and she died. Nice theory, but what if I told you that Mr. Arnz had high nicotine levels, as well. They were both smokers. Still doesn't explain why one lived and one died. Well, I don't know if this is going to help, but the sleeping pills are Zolpidem. Prescription only. I thought I'd save you some time, talked to Lockwood. She didn't have a prescription, but her husband does. Thanks, Greg. 58 00:22:39,958 --> 00:22:42,828 ( rock music blaring ) 59 00:22:51,002 --> 00:23:19,564 Hey, check this out. The red light camera clocked her speed at 52 miles per hour, right? Mm-hmm. The computer software pegged her at 60 by the time she hits the newspaper dispenser. She accelerated into the building. You already reviewed the driver's tox screen. Now you want her basic blood panel. I'm running with a hunch. Let's go. All righty. 60 00:23:24,836 --> 00:23:58,036 SIDLE: Acetylcholine levels were low, epinephrine was high. Why are you focused on those hormones? Kamikaze pilots, World War II-- their bloodwork was very unusual. Acetylcholine levels were low, epinephrine was through the roof. Well, you're talking about the sympathetic response to stress-- eyes dilate, uh, heart rate goes up, hormones go haywire. Diane Lambert lived two hours away. If she drove her car into Vegas with the intention of using it as a murder weapon, I imagine she would be pretty stressed out. Kamikaze Granny.

"If knowledge can create problems, then it is not through ignorance that we will solve them." Is that what you're doing here? Solving problems? It's my job to figure out what happened to your mother. Scientists derive satisfaction from figuring out the puzzle. It's about the quest... not the grail. 63 00:24:40,712 --> 00:24:56,561 ( door bells jingling ) Asimov believed that only scientists could understand the universe. His corollary: "It's not so much that I have confidence in scientists being right..." "But that I have so much confidence in nonscientists being wrong." 64 00:24:58,063 --> 00:25:09,608 You a scientist? Yeah. I am.

It's still an active crime scene. Our lab found Zolpidem in your wife's system-- 20 milligrams. That's twice the recommended dosage. Do you know anything about that? Well... Vanessa was having trouble sleeping. The, uh... prescription is in your name. Are you accusing me of something? No. We're just telling you what we know. 66 00:25:46,978 --> 00:26:17,208 Look, uh... ( sighs ) ever since this discount chain opened a branch down the block, I've been working 16-hour days just trying to survive. And I'd go home, and Vanessa would come at me. You're always tired. You never talk to me. Well, y-You need to communicate with me. You know, I have needs. I'm here all day long. ( echoing ): You never talk to me. She'd just go on and on and on, talking. When she'd finally let me get to sleep, she'd want what every woman wants. 67 00:26:18,343 --> 00:26:30,722 I-I don't mean just sex. She'd want to talk and talk. Next thing you know, it's 5:00 a.m., the alarm is screaming at me, and I got to go back to work. So you drugged your wife to get some shut-eye? 68 00:26:31,723 --> 00:26:52,644 Yeah. I put it in her ice cream. I know it was wrong, but... It's also illegal. Yeah. Happened as an accident the first time. See, I got a problem swallowing pills, so I crush them up in the ice cream. One night, she grabbed the wrong bowl and was out like a light. Best night's sleep I'd had in a long time. 69 00:26:55,046 --> 00:27:23,174 Well, if you... you got nothing else you want to ask, I got things I got to do. I have one more question. When did you quit smoking? I noticed the, uh, nicotine patch on your arm. Oh, uh... about three weeks. Doctor's orders. I got high blood pressure. STOKES: I have another question. Did you know the damper on your chimney was busted? Why? Did this have something to do with my wife's death? I mean, I asked Peter if he'd... ( sighs ) Is this my fault? 70 00:27:24,342 --> 00:27:40,592 If the crash was intentional, I'm thinking either the restaurant was the target, or someone inside the restaurant. I'll call Brass. If Lambert had a grudge against the place, somebody there should know her. If she was gunning for someone specific, there's a lot of variables. Maybe we should start with the most obvious targets-- the people sitting in the window. Let's run it. 71 00:27:41,960 --> 00:27:45,096 Okay... top to bottom. 72 00:27:45,930 --> 00:28:49,461 Cameron Black, deceased; from Jersey. First time in Vegas. Unlikely mark. Second table: Rachel Krandall, and... Tom Krandall. Both died at the scene. Both worked for Sillmont Healthcare. Table three: Hank and... Elaine Alcott. Also works at the insurance company.

Well, uh... could she be one of your policy holders? It's possible. I oversee hundreds of members' accounts. I can check my list. That'd be great. I wish I had some more time off, but, with Tom Krandall gone and half my department in the hospital... I'm back at the office tomorrow. Let's see...

You're out of charcoal. 81 00:31:15,473 --> 00:32:28,346 GRISSOM: In 1939, Isaac Asimov was an undergraduate studying zoology. As part of a course requirement, the students were asked to find a stray cat, kill it and dissect it. Isaac found his cat, he killed it, and then he promptly dropped out of zoology. 50 years later, he wrote that the memory of killing that cat still haunted him. Do you have a question for me? Yeah, I do. Why didn't you fix the chimney damper in your parents' bedroom? Why would I? You told your father you fixed it. So he'd quit bugging me. And if you're accusing me of disobeying a man with only a tenth-grade education, then you're right. We know you took advantage of the broken damper. Placed activated charcoal from your fish tank filter in the back of the fireplace... ( granules rattling ) ...then waited for your father to do what he does every night. You killed your mother, and you almost killed your father. That's good science fiction. Well, you thought the charcoal would burn up, destroying any evidence of the crime, but your father woke up, called 911. 82 00:32:31,549 --> 00:33:05,583 Nick, at what point is the saturation level of carbon monoxide in the bloodstream lethal? Approximately 45, 50%. Hmm. Approximately 45, 50%. Hmm. Well, his mother's level was in the range, but his father's level was low. STOKES: Yeah, but two people exposed to the same level of carbon monoxide for the same period of time, their C.O. saturation levels should be approximate. As long as the variables are consistent-- body mass, health, age. What about smoking? Of course. STOKES: Three weeks ago, your father quit. 83 00:33:07,352 --> 00:33:25,603 Yeah, we didn't know he'd quit, either. The nicotine levels in his system were high, but when we went to speak with him, he was wearing a nicotine patch. STOKES: The patch delivers nicotine to the blood, but since your father quit smoking cigarettes, his C.O. saturation level returned to zero. 84 00:33:28,272 --> 00:33:36,381 You made a basic scientific mistake, Peter. You stopped observing the human element because you thought it was inferior. 85 00:33:37,181 --> 00:33:56,434 STOKES: What I don't understand is why. Man, why would you want to kill your parents? Your high school told us you were accepted to Princeton, early action. A few more months, you would've been 2,000 miles away. Whatever your parents did to piss you off wouldn't have mattered. 86 00:33:59,504 --> 00:34:01,439 I know why. 87 00:34:03,474 --> 00:34:07,044 They weren't going to let you go, were they? 88 00:34:09,714 --> 00:34:24,594 They refused to pay for it. I don't qualify for financial aid because my father makes too much money. Not enough money to live well, but enough to destroy my dreams. 89 00:34:28,632 --> 00:34:36,474 (scoffs) So with your parents gone, you could sell the business and pay your tuition. 90 00:34:38,141 --> 00:34:40,344 You figured out the puzzle. 91 00:34:41,212 --> 00:34:50,121 Must be very gratifying. GRISSOM: Science isn't about the gratification, Peter. It's about the truth. 92 00:34:52,723 --> 00:34:56,194 Hey. Hey. 93 00:35:00,264 --> 00:35:06,671 So, how did it go with Elaine Alcott? She didn't have anything to add to the investigation. 94 00:35:07,839 --> 00:35:36,434 How's it going? Here are the phone records from the driver of the vehicle that you asked for. You know, there may be something to that kamikaze grandma theory of yours. Last week, Diane Lambert closed out her bank accounts, paid off her credit cards, and updated her will. Well, that's certainly more evidence to suggest that her actions were intentional. There's only one Vegas phone number on this statement and the prior statement. There's got to be 80 calls here to the same number. Dial the number. 95 00:35:40,471 --> 00:35:47,512 ( keypad beeping ) ( phone ringing through ) WOMAN: Sillmont Healthcare. How can I direct your call? 96 00:35:49,213 --> 00:35:55,186 What's your address? 16 South Meadows Lane. Thank you. 97 00:35:57,755 --> 00:36:34,592 Right. The Checkerbox is at 16 North Meadows. BRASS: I don't think that's a coincidence. If Sillmont Healthcare was the intended target, how did she end up at the Checkerbox? Well, I'll tell you what happened to me. Last week, I was driving to a crime scene in the car, and the GPS said, "Go right." Had I done so, I'd be coughing up fish from the bottom of Lake Mead. Well, GPS is hardly perfect. Maybe north was a directional default. Or maybe she put in the wrong address. SIDLE: Either way... it does leave one question: Why was Diane Lambert so angry? 98 00:36:37,662 --> 00:37:00,384 Mrs. Lambert was a member of our HMO. I was, uh... going to call you. Well, did she have some kind of problem with her policy? MAN: Not to our knowledge. Then you won't mind if we take a look at her file. I'm sorry. Member files are confidential. Well, this member's deceased. Not even the doctor-patient privilege extends postmortem. 99 00:37:14,365 --> 00:37:19,637 Mrs. Lambert had colon cancer. If you read further, you'll see that it was in remission. 100 00:37:20,938 --> 00:37:30,414 No, actually, her most recent CAT scan shows recurrence two months ago. That's about the same time she started calling your office two times a day. Why would she be calling you? 101 00:37:32,617 --> 00:37:38,522 ( scoffs ) You know what? Four people are dead. Don't waste our time. We can take this downtown. 102 00:37:40,858 --> 00:38:48,693 Mrs. Lambert's oncologist recommended immediate and aggressive treatment. Did treatment commence? The recommendation was pending. Well, what exactly does that mean? Not yet approved, not yet denied. ( engine revving ) ( scoffs ) In other words, Mrs. Lambert's health was in limbo. She wasn't receiving treatment, but she couldn't file an appeal, since you hadn't officially denied her claim. The authorization process takes... It takes time. ( engine revving ) Time Mrs. Lambert didn't have. We have a procedure, and we follow it. ( car accelerating ) And while you were following your procedure and postponing a decision, her cancer cells were multiplying. What were you, playing the odds? Were you hoping she would die before you had to spend a dime? We're not liable here. We're not responsible for Mrs., uh, Lambert's actions. ( engine revving ) ( yelling and screaming ) For what it's worth, that makes me sick. 103 00:38:50,961 --> 00:38:53,330 ( indistinct chatter ) 104 00:38:56,967 --> 00:39:22,626 Catherine. We missed something. SIDLE: Corey, when I was reviewing your grandmother's insurance policy, I noticed that she didn't specify an e-mail address, and that got me thinking. Some people her age aren't technologically savvy. Maybe a GPS device would be intimidating to her. I wondered if she actually even knew how to use it. So I printed the unit, and I found your fingerprints on it. 105 00:39:23,794 --> 00:40:17,948 I installed it. The prints just weren't on the base of the unit. They were on the face. You punched in addresses. Uh... WILLOWS: If you were aware of your grandmother's intentions, and programmed the GPS, you're guilty of aiding and abetting in the murder of three people. What? Oh, God. Uh... Last week, she came by my place 'cause she said she didn't know how to work the GPS. Okay, Grandma, look-- it's really easy. I'll explain it to you again. You just type in the address of where you want to go. ( touch tones beeping ) Look, I swear, if I had known what she was planning, I would've stopped her. Uh... Well... Corey, Homicide has informed us that your grandmother had a life insurance policy in which you're the sole beneficiary. 106 00:40:19,583 --> 00:40:32,563 I... I had no idea. She never mentioned it to you? No. No, no, wait. Promise me. 107 00:40:34,198 --> 00:41:25,049 Okay, fine. When I can afford it, I'll go back to college. You should have a degree. Grandma, I promise. I love you. You're such a good boy. I love you, too. SIDLE: Your grandmother's death has been ruled a suicide, which nullifies the policy. There's not going to be any money. Any money. (scoffs) Now, look, I don't think you understand. I loved my grandmother, but she's dead. She killed herself, and she killed these three other people. Um, what are you telling me? She killed these people for me? And I'm supposed to live with this? 108 00:41:36,727 --> 00:41:40,764 I'll meet you at the car. 109 00:41:41,665 --> 00:41:45,035 I called the lab. They said you were here. 110 00:41:46,170 --> 00:41:52,776 I heard you met Elaine. Yeah. She's really something. 111 00:41:54,879 --> 00:41:58,782 I didn't tell her about us, if that's what you're wondering. 112 00:42:00,184 --> 00:43:07,084 I'm really sorry, Sara. Yeah. Me, too.
