Investigators say Gregory Lacy, 60, hit the children with various objects, including a metal cane and belts. He is also accused of sexually assaulting one of the kids. His wife, LaQuron Lacy, 43, is also facing child abuse charges. Court documents show she often refused to feed them and locked them in their bedrooms.
Authorities investigating a murder at the couple's home uncovered the alleged abuse. A 46-year-old man was shot and killed in their front yard on July 22. No arrests have been made in connection with that murder.
Investigators found that the lower level of the couple's home had been converted into a strip club. Deputies also found Ecstasy pills on a kitchen counter.
The Lacys have seven adopted children, all under the age of 11. The children have been taken by county workers.
