coming up, at first police doubt scott s story. had we missed something? is he the other part of this? reporter: or could he be giselle s next victim? cause let s be honest. nobody likes dealing with insurance. right? see, esurance knows it s expensive. i feel like i m giving my money away. so they re making it affordable. thank you, dennis quaid. you re welcome, guy in kitchen. i named my character walter. that s great. i d tell you more but i only have thirty seconds so here s a dramatic shot of their tagline so you ll remember it. when insurance is affordable, it s surprisingly painless.
if you do it again. this is your last and final warning. why? do you understand me? it s your last and final warning. reporter: inspector ritchie listened to giselle s tone careen from aggrieved to furious to threatening, all in less than a minute. this was far from the subdued woman he d met back in may. it was apparent that she was a violent person. did you ever have any concern about scott s safety? yes. and we advised scott that. if it is giselle, you have to be concerned for your safety as well. reporter: that he might well be a target? yeah. reporter: esteban, it was clear in the recording, had become fixated on her old friend, was convinced michelle had somehow broken up her relationship with scott. and yet, as ritchie took pains to discover michelle and scott were nothing more than just friends. she had a boyfriend. scott was just just one of the many friends that she had. but the only person in this world that seemed to think that there was more to it w
were with scott or had you guys broken up, or no. we were still together. they made the mistake twice. reporter: and then giselle told a strange little story. she was pregnant, remember, with her second child and said she went to the hayward kaiser hospital for a pre-natal check up just hours before michelle disappeared. she said she spotted her old friend at a distance. were you surprised to see michelle there? yes. how did it make you feel when you saw her? at first surprised and then annoyed, and then i thought, okay. keep your blood pressure down. otherwise, you re going to lose this baby. reporter: strong feelings. but giselle esteban herself was not so strong. tiny and pregnant. hardly seemed physically capable of overpowering and murdering the larger michelle le, let alone finding a way of disposing her body. so they sent her home and later
then june 30th, 34 days into michelle s disappearance, the le family contacted us to say they had begun working with a private investigator. a man named michael frame. and in the midst of his investigation, frame sat down with us to tell us what he had learned. this had to happen quickly. this is a public parking garage. people come in and go from that garage all night. someone was lying in wait. they knew that at some point she d return to her vehicle. it was a number of hours before her shift was going to be over. and they were prepared to abduct her at that time. did anybody know why she went to her car? not that we know of at this time. unusual thing to do at that stage of your shift? i think it was either a quick break or something drew her out to her car. that we still don t know. but she was still dressed in her white hospital scrubs. it was evident that she was going to come back because she left her belongings in the hospital. reporter: remember, police found miche
and emails scott gave police. for the better part of six years, she had an obsession with michelle. her text messages were filled with hatred towards michelle at every step of the way. and then towards the the last four months or so, they were filled with hatred towards scott, wishing him wishing his death. wow. they were just filled with hate towards the two of them, with blame towards michelle for ruining her relationship and essentially breaking her family. do you think there s any truth to that at all? only from the standpoint that giselle believed it was michelle s fault. so if, in terms of responding to that question, the answer has to be, yes, there s truth to it. from her perspective but from giselle s perspective, because she had to blame somebody. this is a very disturbed individual. yes. there s no question about that. from my perspective, when we re dealing with in particular
