Louie Sanchez, 29, and Marvin Norwood, 30, both of Rialto, will appear in Los Angeles Superior Court. They were arrested Thursday and held in lieu of $500,000 bail.
The men are accused of beating Bryan Stow, 42, nearly to death in the parking lot of the March 31 game between the Giants and Dodgers.
Eyewitness News acquired exclusive images of two men believed to be Sanchez and Norwood in the stands that night.
The two were charged with one count each of mayhem, assault by means likely to produce great bodily injury, and battery with serious bodily injury.
Sanchez faces a maximum of nine years in prison, while Norwood faces up to eight years behind bars, according to prosecutors. The two are neighbors in Rialto.
Stow's attackers allegedly fled in a car driven by a woman. Dorene Virginia Sanchez, 31, the sister of Louie Sanchez and the wife or girlfriend of Norwood, was also arrested as an accessory. She was released Friday on $50,000 bail. She is scheduled to appear in court Aug. 19, according to Los Angeles County Jail records.
Stow, a Santa Cruz paramedic and father of two, suffered a cut tongue, lip and nostril, and lost an eye. A blow to the head caused brain damage and swelling that prompted surgeons to remove part of his skull. He is hospitalized at San Francisco General Hospital, where he underwent emergency surgery after suffering a seizure due to a build of fluid on his brain.
The case has garnered national and international media attention. Legal experts say it's going to be a closely-watched case.
"You need to establish presence and it appears that the video does indeed do that, but that's just the beginning phase of any case that's built against these two defendants," said ABC News legal analyst Dana Cole of the new images that have surfaced. "I think people here in Los Angeles want to see what the evidence is and everybody is reserving judgment because they know the police made a mistake the first time."
