A senior citizen sits in jail in Jefferson County, charged with raping a four-year-old girl.

Louisville police arrested 73-year-old Charles Greve after the girl told her parents about the abuse. Police say Greve's daughter was baby-sitting the child at the time.

His son says he turned his father in after he admitted to the crime.

"I told him i didn't want to know him no more. T wanted him out of my house, out of my life, gone," said the son, who asked not to be identified. "If he goes to jail, that's his problem. I hope he rots in jail."

Police charged Greve with rape and sexual abuse.
