Newly released details in the attack that outraged baseball fans across the nation indicate that suspects Louie Sanchez and Marvin Norwood initially went after a group of young Giants fans in the stadium parking lot, with Sanchez taking a swing at one of them.

Detectives think he may have hit other fans in the same group, though no one else has come forward.

Then, Bryan Stow and a group of friends walked past as Sanchez stood by his sister's car. Sanchez hit two of them before chasing down Stow and punching him from behind in the side of his head, prosecutors said in a court document filed Monday.

"Stow's friends, who are paramedics, describe that Stow immediately lost consciousness and fell sideways to the ground without breaking his fall," the document states. "When Stow's head hit the ground witnesses heard his head impact the concrete and saw it bounce."

Sanchez then kicked the unconscious Stow several times in the head while Stow's friends tried to shield him with their bodies, prosecutors said.

Norwood is also accused of kicking Stow then standing over his prone body and saying, "Who else wants to fight?"

The document, filed as part of a bail reduction hearing for Sanchez, provided the fullest account yet of the attack that left Stow near death and has kept him hospitalized for four months.

Sanchez, 29, and Norwood, 30, have been charged with mayhem, assault, battery and other counts in the beating of Stow. On Monday, a judge continued the request to reduce bail for Sanchez from $500,000 to $100,000.

Arraignment for both men was set for Aug. 10.

Matthew Lee, one of the men with Stow who was also attacked, was going to be a witness but died over the weekend from an allergic reaction after eating a peanut, police Cmdr. Andy Smith said.

The document portrays Sanchez as leading a rampage against Giants fans during and after the March 31 game.

The trouble started inside the stadium, when Sanchez threw a soda at a woman. When her companion yelled at Sanchez, Norwood had to hold Sanchez back to stop him from attacking the man, the document states.

Prosecutors also provided photos of weapons and ammunition they said were seized at Norwood's house, including an AR15 rifle with a scope, pistol-grip shotgun and revolver.

Norwood allegedly told police he was holding the guns for Sanchez because Sanchez could not keep them at his parents' home where he was staying.

Sanchez's attorney, Gilbert Quinones, said he had not seen enough evidence in the case to comment.

A woman who answered the phone at Sanchez's home hung up without commenting Monday.

Last week, Sanchez's father Luis Sanchez said he was frustrated with media coverage of the case and wanted to speak out but had been told by lawyers not to.

"It's on the tip of my tongue. I want to, but no comment," the father said at the family home on a quiet cul-de-sac in Rialto, east of Los Angeles.

A message left at the home of Norwood's mother home was not immediately returned.

Prosecutors also outlined Sanchez's criminal past. His adult rap sheet includes battery on a spouse or cohabitant in 2003. He completed a yearlong domestic violence course as part of the case.

In 2004, he was arrested for carrying a loaded firearm in a car and the following year he was convicted of driving under the influence.

In 2005, he was arrested again for DUI after leading police on a high-speed chase through a residential community.

"It is clear from the crimes charged and from his criminal history that defendant Sanchez is completely incapable of controlling his behavior or obeying court orders," the document states.
