Tyron Rozier Jr. was 17 and from Philadelphia when he was shot and killed on July 4, 2021. He was found suffering from a gunshot wound on the 2100 block of West Sedgley Avenue at about 11:21 p.m. and was pronounced dead shortly after arrival of medical personnel.

Investigators say the probe produced public tips and forensic leads that pointed to James Adams, 23, who was arrested January 5, 2024, and charged with murder and related offenses. Authorities allege Adams used a 9mm ghost gun in the killing. Adams is in custody without bail and a preliminary hearing is scheduled later this month; the case remains pending trial.

The District Attorney’s Office cited the role of advanced forensics and interagency work in making the arrest. If anyone knew Tyron, saw activity on West Sedgley Avenue that night, or has information relevant to the investigation, please come forward.
