This is, by a wide margin, the most bizarre crime story ever

Remember that pizza delivery guy about four years ago who was "forced" to rob a bank and, when cornered by the police, an explosive collar around his neck detonated? According to this ABC News story, the police are about to make an arrest and the suspect is about the last person you'd imagine: a female, former valedictorian, with psychiatric problems:

Nearly four years after one of the strangest murder cases in federal law enforcement history, authorities appear poised to announce indictments in the case of the pizza bomber as early as Wednesday, sources tell ABC News.

Sources say the indictments will center on a former high school valedictorian with bipolar disorder who is believed to be the ringleader of a bizarre Pennsylvania bank robbery gone bad. What remains vexingly unclear is whether pizza-delivery man Brian Wells was involved in the plot in any way.

Stay tuned. (HT: Ace)

Update (7/11) - From CNN: "Woman at center of bizarre plot with collar bomb" It seems she needed the pizzaman to rob the bank so she could hire a hitman to kill her father. You heard me.
