this is how nicole cook rationalizes it. >> she walked away. she got up and left. i saw her walk away. i saw her leave. >> what sort of shape did she seem to be in? >> i don't know. she didn't seem -- i can't really remember. i only saw her for a second. >> coming up, lots of witnesses, but not many answers in what is soon to be a case of murder. >> 3:00 in the morning when they came, the police officers said there were two fights and reena went in the water and is presumed dead. that is all they told us. >> when "bloodlust under the bridge" continues. the other office devices? they don't get me. they're all like, "hey, brother, doesn't it bother you that no one notices you?" and i'm like, "doesn't it bother you you're not reliable?" and they say, "shut up!" and i'm like, "you shut up." in business, it's all about reliability. 'cause these guys aren't just hitting "print." they're hitting "dream." so that's what i do. i print dreams, baby.
