A judge on Wednesday ruled that there was enough evidence for 20-year-old Arkel Garcia to proceed to trial on murder, robbery and related charges.
Christian Massey died on November 30 after police say a gunman demanded his new Beats by Dr. Dre headphones, which cost at least $200.
Massey refused and was shot several times. Officers who found the 21-year-old victim say he told them what happened before dying at a hospital.
Prosecutors showed surveillance video in court of Garcia allegedly following Massey before the shooting.
They claim the video disputes Garcia's claim that an accomplice shot Massey.
Massey graduated last summer from Marple Newtown High School. The special education student had been a beloved member of several sports teams.
Garcia's attorney said his client maintains his innocence.
