Son charged in slaying of 67-year-old South Fayette mother

The son of a 67-year-old South Fayette homicide victim was arrested Saturday by Allegheny County Police.

David Sumney, 30, was charged with criminal homicide, robbery, theft and abuse of a corpse in the death of his mother.

The victim’s body was discovered Sept. 2 when South Fayette police responded to 172 Olde Orchard Drive for a welfare check. Officers entered the home and discovered the resident deceased. A news release from the Allegheny County Police did not identify the woman by name.

The Allegheny County Medical Examiner’s Office performed a post mortem examination the next day and ruled the cause of death was blunt force trauma.

Homicide detectives identified Sumney as a suspect. He was arrested Sept. 4 and charged with receiving stolen property after he was found to have jewelry belonging to his mother. Sumney was lodged in the Allegheny County Jail in Pittsburgh on those charges.

Anyone with information concerning the slaying is asked to call the Allegheny County police tip line at 833-ALL-TIPS (833-255-8477). Callers may remain anonymous. The department also can be reached via its social media sites.
