Jeff Duhamell. "We're trying to confirm exactly how much she knew, but she is cooperating with us on this."Officers recovered money they believe was taken from the bank, along with other items investigators think link him to the robbery during a raid of the home where the family lives, near 10th Street and County Line Road.Investigators said Oliver has lived in the home for four years.One neighbor said she was shocked by the allegations."It's really difficult to think that. I mean, I've known her for many years, and I've known him for quite a while, and it's hard to think that somebody could do that," the woman said.Two armed men, wearing wigs and masks, went into the at about 11 a.m. Saturday, demanding money.One of the men grabbed the girl at gunpoint and held her in a headlock. The men left the bank with what authorities described as a substantial amount of cash.A neighbor told 6News Thursday that Oliver paid off a $1,000 debt in the days after the robbery, and a former clerk said Oliver had been buying hundreds of dollars worth of lottery tickets at a nearby convenience store.The girl was not injured in the robbery and returned to school on Thursday.Oliver is not the girl's father, although she referred to him as dad, police said. He had been arrested Thursday on a warrant in an unrelated incident. Watch 6News and refresh this page for updates.
