Philadelphia police are investigating after an elderly couple was found dead overnight in their Strawberry Mansion home.
Authorities were called to the 2500 block of North Spangler Street around 1:30 a.m. after a relative of the pair found them inside.
It wasn't immediately clear how the 66-year-old woman and 79-year-old man died, or whether foul play was involved.
The police department's homicide unit was called to the scene, but no determination had been made early this morning on whether the two were killed.
Homicide investigators said they were waiting for the medical examiner to conduct an autopsy.
There were no obvious signs of trauma to their bodies, police said.
