An unemployed gardener with a history of mental illness was a vital witness in the case

of a missing six-year-old girl.

He's still working on me.

Between songs, he provided details about events which took place more than a decade earlier.

Investigators weren't sure the man could be trusted and left it up to forensic science

to determine the truth.

Memorial Day weekend, 1986.

In Silver Spring, Maryland, it was so hot, six-year-old Michelle Doar asked her father if she could

play in the small pool in their backyard.

Michelle and me have, she could blow bubbles in the water and that sort of thing.

Michelle was spending the weekend with her father.

Her parents were going through a bitter divorce and custody arrangements for Michelle, their

only child, were still being worked out.

Michelle's mother, Dee Dee, wanted full custody of her daughter.

But those problems were put aside for what Carl believed would be a pleasant weekend with

his daughter.

her friend Elizabeth, but they hadn't seen her.
