This week, the remains were confirmed by Virginia State Police as 44-year-old Tonya Slaton’ biological son Quincy Jamar Davis, according to WTVR.

One investigator believes “the victim’s death was likely the result of some homicidal action.” The cause and manner of the boy’s death are still under investigation.

Police would not say when the boy died, but have no knowledge of his welfare since 2004. No missing persons report was ever filed for Quincy.

Police initially pulled Slaton over Hampton for driving with expired tags. A subsequent inquiry revealed the car “was not registered in Virginia and the license plates on the vehicle were not found on file with the Department of Motor Vehicles,” according to the affidavit.

The trooper began impounding the vehicle and while taking inventory, discovered a black trash bag in the trunk. There was a strong odor of rotting flesh permeating from the bag, police say. The body was reportedly double-bagged and sealed with duct tape.

Slaton allegedly threw some clothes on top of the bag, and told the trooper the bag contained clothes. The trooper also noticed a large white stain located on the floorboard behind the driver’s seat and Slaton told him she spilled bleach,  according to the affidavit.

Slaton has been charged with concealment of a dead body and is being held at the City of Hampton Jail without bond.

Police say further charges are pending.
