A shooting as the Warriors game let out Thursday night left two fans dead - the driver of a Porsche was killed by bullets and the passenger was killed as he staggered out onto Interstate 880 in Oakland.

Now, police are turning to Warriors fans and nearby surveillance video from the O.co Coliseum for help in finding the killers. Oakland police spokeswoman Johnna Watson said Friday that the two men were leaving the arena about 10:35 p.m., when the shooting broke out.

The victims were identified late Friday by the Alameda County coroner's bureau as Christopher Beardon, 30, of Pittsburg and Terrance Marks, 28, of Richmond. Authorities said that it appeared as though they were heading home to Contra Costa County.

The men were wearing Warriors clothing and had tickets to the playoff game on Thursday, which were found inside their 2010 Porsche Panamera, Watson said.

Police said it appears as though people in two cars were shooting at each other. The people in the second car have not been found. On Friday, witnesses told authorities the second car may have been a dark-colored SUV.

The driver was killed by the bullets, authorities said, and the passenger was killed when he was struck by an oncoming car - he had staggered out onto the highway after the bullets whizzed into the Porsche.

California Highway Patrol spokesman Sam Morgan said his officers were processing the highway at Jackson Street, looking for shell casings to collect more evidence. Oakland police will be handling the homicide investigation.

The freeway was shut down for hours, causing major traffic backups for people leaving the Golden State Warriors game, where the team lost, 94-82, to the San Antonio Spurs in Game 6, ending their season. The highway was re-opened at 2:30 a.m. Friday.

The pair of killings brought Oakland's homicide numbers up to 37. Last year at this time, there were 46.

Police and Crime Stoppers of Oakland are offering up to $20,000 in reward money for information leading to the arrest of the killer. Anyone with information may call police at 510-238-3821 or a tip line at 510-773-2805.
