The woman whose body was found partially buried in the backyard of a building on the 4700 block of Frankford Avenue died of stab wounds, Philadelphia Police spokeswoman Christine O'Brien said Thursday.
Police have not released the woman's name, nor the name of a suspect.
The body was found Tuesday morning behind a three-story building, the woman's toes sticking out of the dirt. After police saw a man looking down at them from his second-floor apartment, he tried run out the front door - but officers Tasered him and took him into custody.
Police had been led to the body by a man who flagged down a foot patrol officer around 11:30 that morning.
