Camden County Prosecutor's Office spokesman Jason Laughlin says 20-year-old Ryan Coyle died Friday night at Cooper Hospital in Camden. But a cause of death has not been disclosed.

Authorities say the victim fell and hit his head on the pavement when an acquaintance came up behind him and punched him. Authorities have not said what sparked the fight, which occurred in a parking lot before Tuesday night's concert at the Susquehanna Bank Center in Camden.

The alleged assailant, 21-year-old Matthew Shields of Westville, has been charged with aggravated assault. Laughlin says prosecutors haven't decided whether Shields will face upgraded charges following Coyle's death.
