car, put the handcuffs on him. no hysterics, no profanity, typical, you know, scott, you know, his controlled, you know, demeanor. reporter: what they found in the car with scott was fascinating. camping gear, four cell phones, his sister s credit card. his brother s driver s license and cash. almost $15,000 in cash reporter: in cash. he also looked different. way different. by intent, clearly. when you arrested him, did he express anything that would suggest he understood that that was it, he was going away? i went to search his car, he said jon, can you tell me if those bodies were my wife and son? and i just told him. i said, scott, you already know the answer to that. reporter: as they drove north to modesto with their prisoner in the back seat, buehler got confirmation that the dna was in, the bodies were connor and laci. they told scott. now he s wearing sunglasses at the time. i look and i can t he doesn t make hardly any reaction whatsoever.

crying, he didn t have to kill her. and that changed everything you d ever thought about him? it did. reporter: detective buehler had told sharon about amber because rumors were in the air. the media was sniffing about and getting close. i get to the office, a reporter was right there. oh, boy. yeah. reporter: january 24th, local news showed up at amber s workplace. the national tabloids were not far behind. did you talk to them? no. i refused to talk to anybody. reporter: trapped in her office, she called detective buehler. that s when the modesto pd decided, that if amber s story was going to break anyway, they d break it on their terms. we believed at the time it was probably best to get her up there, almost like exploding your own bomb. reporter: buehler sent two colleagues to fetch her with a statement all prepared. we were speeding back, in a sense, getting there. and you know, having this statement written out, you know, trying to read it a few times,
