and i asked him to take me to the boat. show me the boat. reporter: very late that first night, the detective and scott went to scott s warehouse, where he worked and kept his boat. you came here that night, right? christmas eve night, yeah. reporter: what did he tell you when you came here and you wanted to look inside and you had your flashlight out and stuff? he said, there s no electricity. reporter: no lights, which was a lie. so i just said, open the door, and i ll put my headlights in there. reporter: to the detectives it all smelled bad. so they did the things detectives do. they got a wiretap on scott s phone, hid a gps under his car, and they watched him constantly. sometimes they noticed he watched them, too. i was surveilling him and i m in an unmarked car. i m parked three blocks away in a high school parking lot full of cars, and i m watching this place with binoculars. and all of a sudden, i look in my side view mirror, and scott. so i got out of the
and yet he seemed such a boy scout. he had no secret criminal past. listen to the wiretap on scott s phone. hi, scott. this is mom. it was a boat anchor. we knew it wasn t laci. that is scott whistling in the background. he seems relieved, too. i just dodged that one. you can interpret that in, good, that wasn t laci. that was lucky it wasn t her. suggesting to us we were looking in the right spot. and yet, he seemed such a boy scout.
golf at the club. reporter: he said he drove to his warehouse office a few miles away . and you want over to your shop? right. and what d you do over there? i assembled my mortiser. know what a mortiser is? no. it s a woodworking tool to make tables. yeah. i just got that, so i assembled it. checked my email. sent one email. then hooked the boat up and went. reporter: then, said scott, he drove to the berkeley marina about 90 miles away, parked his car, and put his boat in the water. when you got in your boat and you took off, did you go very far, or well, i mean, probably a couple miles.
right at him. they asked scott to come down to the police deparment again. and without telling him where they got it, they showed him a fax of a photo of himself with amber frey at the christmas party. and of course he lies when he s confronted. reporter: prosecutor birgit fladager. he sees the picture of himself with amber and he says, that s not me. was it clearly him? it was. reporter: if scott suspected the detectives had somehow found out about amber, he didn t let on. and he kept calling her, and she kept recording. but he started testing her with questions. did you see that news on paris? no, i didn t actually. there was a bomb that exploded. and i was like, what bombing? there was another time he had asked if i had seen the article on the monarch butterflies that are in pismo, and i said, no. i gathered right away he was asking because these were in fact something that was in the paper possibly. right.
