The Port Richmond community is grieving the loss of Riley Costello, a 21-year-old hairdresser, and her father, Jeffrey “Jeff” Costello, 58, whose deaths have left those who knew them struggling to comprehend an unimaginable tragedy.
Philadelphia police were called to a residence on the 2800 block of Mercer Street at about 1:30 p.m. Saturday after family members and others became concerned when they could not reach the residents. Officers subsequently found Riley and Jeff inside the home with gunshot wounds. Both were pronounced dead at the scene.
Police are investigating the deaths as an apparent murder-suicide. Investigators believe Jeff fatally shot Riley before taking his own life, while the motive remains under investigation. Police Inspector D.F. Pace said investigators believe the shooting may have occurred several days before the bodies were discovered.
For Riley, her death represents a life and future cut painfully short. At 21, she was building a career as a hairdresser and forming connections through her work and community. Details about her education, career history and personal interests have not been publicly confirmed.
Jeff was 58, but additional details about his career, personality and personal history have also not been publicly confirmed.
The circumstances surrounding their deaths have deeply affected Port Richmond, where neighbors expressed shock at the tragedy.
As authorities continue their investigation, Riley’s life deserves to be remembered beyond the circumstances of her death. She was a young woman with a future ahead of her, while Jeff was her father and part of a family now facing profound grief.
Their loss leaves a painful absence, and those who knew them will carry their memories forward.
