4 shot after gunfire erupts at party in Philadelphia's Olney section

PHILADELPHIA (WPVI) -- Philadelphia police are investigating a quadruple shooting in Olney early Monday morning.

The calls started coming in shortly after midnight.

Investigators say there had been a party in a garage in the alleyway between Marwood Road and Clarkson.

An argument erupted in gunfire. At least nine poeple shots were fired.

Arriving officers initially did not find any gunshot victims but located a 16-year-old in a nearby ambulance at Marwood Rd. and Geneva Ave.

Witnesses directed officers to a house where they found a gun, which the witnesses told police was stashed there by the teen in the ambulance.

The teen was transferred to Saint Christopher's Hospital with a gunshot wound to his leg.

Police then started to get calls for walk-in victims to Temple University Hospital.

Officers located the car that three men arrived in.

Two victims are 34 years old, and another is said to be 30. All were in stable condition.

One of them is believed to also have been involved in the shooting.

"One of the males over at Temple, through video evidence acquired by officers on the scene, appears to be involved in the shooting as well, and at this time he is being detained," said Captain Louis Higginson, with the Philadelphia Police Department.
