Philadelphia police are investigating the discoveries of three women found fatally wounded overnight.

Police also released the name of a man gunned down early yesterday afternoon in West Philadelphia.

Last night, around 11:40, a 16-year-old girl was found dead on the second floor of a home in the 4900 block of Hoopes Street.

Police have witnesses, some ballistics evidence and a suspect, but no arrest has been made, said Homicide Sgt. Tim Cooney.

The identity of the victim was known but was being withheld, he said.

About 6:15 this morning, two women were found stabbed to death in a house in the 2100 block of South Seventh Street.

No ages or identities were available, as police were still investigating at the scene, Cooney said.

Yesterday's lunchtime shooting left a man dead and a women wouded at 40th and Poplar Streets.

Robert Fuel, 26, of the 3900 Poplar Street was shot in the face and was pronounced dead at the scene at 12:59 p.m., DiDonato said.

The woman, 18, was initially in critical condition at the Hospital of the University of Pennsylvania, but her condition was later upgraded to guarded, DiDonato said.

She was shot in the back and shoulder.
