Jason Laughlin, spokesman for the Camden County Prosecutor's Office, said that about 2 a.m., Corona confronted the victim, Eladio Castro, 36, also of Camden, who was sitting in his 1996 Chevrolet Astro van outside a crowded party on Vine Street.
Castro, who had attended the party, was pronounced dead at 5:45 a.m. Detectives are still sorting through information to establish a motive.
A 25-year-old man, also from Camden, was injured by a stray bullet. His identity was not released, and authorities did not say whether he knew the victim.
Corona was picked up Thursday by officials from the U.S. Marshals Office.
In asking for the high bail, Camden County Assistant Prosecutor Ira Slovin said that Corona remained a flight risk, that he had a criminal history that began when he was a juvenile, and that prosecutors had a strong case against him that included witness accounts.
Castro's killing was the 26th homicide in Camden this year, compared with 20 during the same time period last year, Laughlin said.
