This morning, I was contacted by a woman who, like Amy, received strange phone calls, in 1989. She says the FBI came by her home in 1995 and collected paint scrapings from her father's...blue van. At the time, they said they were taking it to possibly match against material in Amy's case.
If the FBI were interested in blue vans, did they take paint scrapings from Dienes' blue van, too?
