2000 and 2001, he had a job site in santa clarita. you can t tell now, but back in 2001, there was a major construction site. chris had told police that he did not work for his dad that winter when he was on unemployment. but larry saw some big cash deposits going into chris s bank account in addition to his unemployment checks. he thought that chris might have been working for his dad off the books. and larry came up here to ask around. and they told you that it was chris s father s construction company? chris s father did some of the tractor work at that site. reporter: and chris worked there? and chris was one of the tractor drivers that the superintendent said was there every day. reporter: is this where you thought to yourself, that s where lynsie eckeland is? i thought chances were excellent that if i killed lynsie and i was in chris s situation and i had use of a tractor out in the middle of
didn t trust because of his secret relationship with lynsie, and because he had lied about his identity. and the man who dropped lynsie off at that corner, the last american to see her before she vanished, chris mcamus. april 2002. more than a year after lynsie went missing. detectives decided to start over. they brought chris back to see if his story still held up. i really would like to think that lynsie has been like either abducted or something has happened to her. like what? i would really rather think that she was with a friend or things like that. police turned up the heat. let s cut the bull about being positive, and get down to the nitty-gritty, if it were a perfect world, that she was
road again. reporter: he watched the february 2001 interview that police did with a very unhappy marty. doesn t it strike you as tremendously suspicious that marty would call after lynsie disappears, talk to lynsie s mother, and give a phony name? if you didn t know the background of marty, then absolutely. when i talked to the mother on the phone i just gave her an identifier, okay? marty rossler, that s what i said, all right? which is a lie. which is a lie. reporter: watching that interview, larry chalked up marty s dishonesty as an attempt to save his marriage. i don t want my wife to be brought into this thing. reporter: larry also took a closer look at the idea that marty and lynsie were together at that clothing store after she went missing. i flat wasn t there on that day, okay? reporter: no one ever found any security video of that, and larry s learned over the years that well-meaning people often
at times on video and sometimes just on audio tape. when is the last time you saw lynsie? a week ago. no. i don t think so. absolutely. no. absolutely not. marty said that he had last seen lynsie the day that she went to san diego on that friday. reporter: did you believe him? we really didn t believe him. reporter: they didn t believe him because a clerk at a local clothing store had called to say she had seen lynsie with a much older man who matched marty s description together at her story after the day lynsie went missing. i flat wasn t there on that day, okay? i have been in that store, all right? i said, i m like you, i m easily, you know, identified, okay? probably every place i ve been with her would know that i was in there with her, okay? it was a very long, very long interview. reporter: friendly? no. no. i remember drilling down on him,
because the atm photo that at first fooled investigators actually proved chris wasn t there. it wasn t your truck. but for years, it was thought that it was your truck. it s not. as a matter of fact your truck did not go by that night. it wasn t there. reporter: he told chris about the credit card statement and how he found someone who remembered chris working on the job site. all of a sudden, big red flags. you are working. you re out there when you said you were not. but he said you guys don t work on saturday. lynsie disappeared on a saturday morning. none of your credit card usage up there is on it, any weekend. all of it is on weekdays except for the day lynsie disappeared. reporter: he told chris the lie about lynsie being found. we went recently, found dna and had that checked against the body and it s lynsie.
