A woman walked into her sister's North Philadelphia home late Tuesday night and made a ghastly find, cops said: her 52-year-old sister slumped on the couch, dead of severe blunt-force head trauma.
Medics arrived at the scene, in the living room of a rowhouse on Gratz Street near Susquehanna Avenue, and pronounced the woman dead at 10:50 p.m. They were unsure how long she'd been dead, but relatives told investigators they'd last seen the woman around 8 p.m.
Police said there was no sign of forced entry into the house and were unsure if anyone else lived there with the woman. Police found a weapon they believe was used in the murder inside the house early Wednesday morning.
