PHILADELPHIA (KYW Newsradio) — Philadelphia police say they have arrested another suspect in connection with the shooting outside Roxborough High School last month that left a 14-year-old football player dead and four others wounded.
Around 6 a.m. Thursday, police went to a home on West Albert Street in North Philadelphia to serve a warrant. They arrested 17-year-old Zyhied Jones, who now faces murder, aggravated assault conspiracy and weapons charges.
Jones is the second suspect in police custody.

On Wednesday, police arrested and announced murder and related charges against 21-year-old Yaaseen Bivins for his role in the shooting on Sept. 27.
Investigators say they found a receipt that linked Bivins to the shooting. Police say it was for the purchase of ammunition, the same ammo that was found at the shooting scene.
A third suspect, 16-year-old Dayron Burney-Thorn, is still at large.
Investigators don’t believe he’s in the area, so U.S. Marshals are involved in the search. Anyone with information is asked to contact police.
Police say there were two cars involved in the shooting. One was parked at the corner of Pechin and Gates streets for about six minutes before five gunmen jumped out and opened fire.
The shooting wounded four students between the ages of 14 and 17, and killed 14-year-old Nicolas Elizalde from Havertown as he was leaving a football scrimmage at the school that day.
