It was August, deep end of the summer of 2003, when 19-year-old Casey McLeod disappeared without a trace.

Casey's mom, Lori, and her father, Rob McLeod, had divorced when Casey was four years old, but Rob remained very

involved in his daughter's life. He described her to Dateline as a happy and normal kid who did

well in school and loved life. But, like a lot of teens, Casey got more rebellious as she grew up.

She started hanging out with a crowd that her parents didn't really approve of. And at some

point, after graduation, she started using methamphetamine. Unfortunately, Casey's meth use meant that

she would disappear for periods of time and that her behavior became pretty erratic. But eventually,

Casey turned things around. She got clean, got off drugs,

and got a job at Subway. Her dad, Rob, told Dateline that he was massively proud of his daughter.

Another male influence in Casey's life was her mother's boyfriend, 36-year-old Scott Kimball.

Casey's mom, Lori, met Scott Kimball at a casino in Black Hawk, Colorado, earlier in 2003.

At the time, Lori was 39 and working at a hair salon.

The story that Lori told Dateline was that she saw Scott pushing his mother around in a wheelchair. She kind of took

this as a sign that Scott was a nice and caring guy. Ironically, the very first thing that

Lori said to Scott was, you're not a felon, are you? That's when he told her that he was an FBI

agent. Lori didn't realize at the time how close her kind of joking pickup line hit to home.

She had no idea that Scott Kimball had just gotten out of prison, where he served time for financial fraud.

In fact, he got out in December of 2002, just a couple of months before he met Lori.

Scott told Lori that he was divorced and had two sons. At the time, he was living with his mother

and her girlfriend. Lori told Dateline that Scott did romantic things for her, like buy her flowers,

and he always seemed to have a lot of cash in his hand.

He spoiled her and her daughter Casey.
