A Los Angeles court Friday publicly released video of one the two suspects in the Bryan Stow beating case admitting to being connected to the Dodger Stadium attack.

In the video, which was shown in court Wednesday, suspect Marvin Norwood talked to his mother on his cellphone while in police custody and told her he was involved in the incident.

Legal experts said the video could be the most crucial evidence in this case.

Both Norwood and Louie Sanchez have pleaded guilty to charges in the attack on Stow, a Santa Cruz paramedic, that occurred on 2011 Opening Day.

Stow was severely injured in the attack and doctors said he would need life-long care.

The two suspects were in the courtroom Friday as Alan Bradford, one of Stow's friends, who was at the game the night of the attack, gave his account of what happened that night.

Bradford testified that two men, resembling the defendants, attacked Stow and his friends twice. Both times were unprovoked, he said.

Stow got hit the hardest, Bradford said.

"He was going straight back. His arms were limp out behind him, like gravity had taken him, and it was like a tree falling," Bradford said in his testimony. "There was no movement, and he wasn't able to put his arms out to break his fall."

The defense, in its cross examination of Bradford, questioned his perception of the events

Defense attorney Victor Escobedo asked Bradford how many beers he drank that night.

"At the hotel, prior to the game, maybe three or four," Bradford said. Bradford then said he had three additional beers at the game.

The preliminary hearing will resume Wednesday, when another member of Stow's group from the game is expected to testify.

A judge will decide after the hearing if there is enough evidence to send them to trial in the Stow beating.

The case is fraught with undercurrents for the city, where Dodger Stadium has long been a baseball landmark. The beating prompted public outrage and led to increased security at Dodgers games.

Lawyers for Sanchez and Norwood have suggested they might have been involved in other altercations that day, but not the attack of Stow
