the football star, zach, had been drinking, and he had two different prescription meds in him, so, he was pretty seriously impaired. he's not denying he killed daycia. he pretty much confessed. he says he blacked out. so, you're thinking that zach's not responsible for the murder? according to the doc, the drowning was staged by pumping her body full of water. now, if that's the case, that means the killer had to feed a tube down her trachea, into her lungs. that's not an easy thing to do. basically had to intubate her. i've seen er docs struggle to do this. it takes dexterity, at the very least. zach was drunk and full of meds, so, no way he could have pulled that off. finlay: if zach is not the killer, where are we? we know that adam brought daycia home in the cab at 3:00 a.m., and says that he put her to bed. come on, adam!m i'tinot red! everybody's trying to sleep, okay? yeah, well, i'm not gonna be able to go to sleep. okay, well, let's just try to get you in bed. stokes: and we know that da ayciwasn't ready to call it a night, so she goes and convinces zach

that it's a good time to take a bath. you don't see anyt hingat th w yo? come on, zach. in they go into the tub, they havx,e se leaving the marks on daycia's neck, and the scratches on zach, but, also, leaving daycia alive and well. stokes: tub takes 45 minutes, at the most, an hour. that gives the killer plenty of time to take care of business. so, not counting zach and adam, there were three other people in the house that we know of. there were two patients-- karen and len-- and a staffer named twyla. at this point, any one of the three is a candidate. morgan? hey. hodges, what's going on? i could use a little help as to context. doc robbins found a foreign substance in your victim's lungs, sent me a sample for analysis. okay, what did he find? it's all organic. primarily a combination of nitrogen, phosphorus, potassium and carbon.

some of the nitrogen had converted into ammonia. how can i help? well, it's just that what's suggested by the chemicals and their particular proportions is waste. specifically, fish or bird waste. now, i don't know how that could have gotten into your victim's lungs. fish waste. but that doesn't make any sense. actually, hodges, it makes perfect sense. ah. look at this. tubing. looks like it would be the right size to put down someone's throat. yeah. now, all you would need is a... pump... (pump whistles) to pump with. the same set of prints shows up on everything. they come back to the house therapist, twyla owens. oh, you said that she took care of the fish tank,

so it makes sense that her prints would be everywhere. well, everywhere except for the plastic tubing. there were no prints there. it's been wiped clean. and what about the pump? has tons of her prints on it, and nobody else's. why would the killer clean one and not the other? oh. because the killer didn't use the pump. there's a crack in the housing. yeah, and it's bone dry. there's no way this was part of the murder weapon. yeah, but the killer had to use something to force the water into daycia's lungs. i mean, doc said her alveoli were popped like balloons. well, then, maybe the killer pumped the water the same way that you'd blow up a balloon. maybe he used his mouth. if that's the case, maybe our killer left us just what we need.

come on, this is insane. this is absolutely insane. i'm two days away from completing the program. two days away from... holding my kids in my arms again. is this some kind of sick joke? look, daycia's death had absolutely nothing to do with me. says here that you worked as an emt in college. is that right? yeah. taught you how to intubate a patient, didn't they? yeah. yeah. so what? too bad they didn't teach you about dna, because you left yours all over the tube there when you blew in it. we also found the pillow that you used to suffocate daycia. look, we have everything we need. we know you did it. of all the people in that house, you were the one with the most to lose. why would you do something...? because i had the most to lose, because... because of my children.

you know what daycia was? day-daycia was that, um... she was that little devil. and the little devil sits on your shoulder, tempts you to do bad things. so, wait. what are you... what are you saying? wh... daycia tempted you in some way? what? with alcohol? i woke up... to go the bathroom in the middle of the night. it must have been just past 4:00. i got back to my room. there was a bottle sitting on my nightstand. a bottle of bourbon, my brand, with a damn ribbon on it. and-and you think that daycia put it there. i know daycia put it there. like i just told you, she was that little devil. so, i got up, and i went, and i confronted her. what the hell is this, daycia? why did you put this in my room? geez, len, lighten up. it's a gift. you know how important the program is to me, that i stay clean so i don't lose my kids.

you know you want some. stop it. don't make me drink all by myself. mmm. she wouldnto't sp. she wouldn't back off. she just kept at it. she kept trying to get me to drink. look, all i wanted to do was shut her up. with the pillow, i mean. i mean, come on, it was a pillow. i put it over her face just to get her to stop talking. stop it! stop it! no, stop! fl(mufed scream) i've worked too hard. i'm not gonna throw my life away. (whispering): i'm... sorry. the bathtub in daycia's room was already full, so i thought, why not... why not just make it look like an accident? make it look like she just... slipped away.

i put he tr inathe wer. i got the piece of tubing from the fish tank, and i made it look like she drowned. insane part of this whole thing is, i made it, you knoatw th? i didn't drink. even after she was dead... (crying): ...and it was quiet in that room. i took that bottle, and i poured it in the toil... toilet. (sniffles) i didn't touch it. (sighs, sniffles) i didn't take a sip. i needed to do that. (sobs) for them. (sighs)

finlay: so, we are just about cld eareout, and i'm officially releasing the rooms. good. we got two new patients coming in. wow. you don't waste any time, do you? we can't afford to. a lot of people need help. you know, i-i was really harsh the other day when i talked to you about daycia, and i shouldn't have been. she didn't understand her addiction. didn't realize that she was battling a disease. most people don't. patients come in here thinking all they have to do is put in the time. beating addiction is work. really hard work. and sadly, not everyone's up for the challenge. well, i don't know how you do what you do. i was gonna say the same thing to you. guess we just keep doing it, though. if we don't, who will? hmm. good luck. captioning sponsored by cbs,c.s.i. productions, and toyota. captioned by media access group at wgbh access.wgbh.org
