The two suspects arrested in the Bryan Stow beating case were due to be arraigned this morning. Meanwhile, details of the police investigation leading up to the arrests emerged.

From the LA Times this morning:

The two new suspects accused in the Dodger Stadium beating of Bryan Stow bragged to coworkers after the attack, police sources said. Police said they were able to identify the men from Rialto — Louie Sanchez, 29, and Marvin Norwood, 30 — based in part on their unruly behavior at the March 31 game and after they bragged to coworkers about their fights. The men were charged with assault and mayhem Friday afternoon and were being held on $500,000 bail. They are scheduled for arraignment Monday morning.

The police sources said they have cellphones and photos that place the men at the game. In addition, the men were implicated by Dorene Sanchez, Norwood’s wife or long-term partner, and Louie Sanchez’s sister, the sources said. Dorene Sanchez was arrested as an accessory to the crime, but has not been charged. She appeared before the grand jury on Friday.

Dorene Sanchez was arrested as an accessory, but has not yet been charged.

KABC Los Angeles on Saturday showed the two suspects in background images from a home video taken at opening day at Dodger Stadium. Stow was attacked outside the venue after the game.

The complaint against Norwood and Sanchez also included some grisly details about the attack. From AP:

The complaint alleged both men personally inflicted great bodily injury on Stow, “causing him to become comatose due to brain injury and to suffer paralysis.” ~~The mayhem count alleged that they “did cut and disable the tongue, and put out an eye and slit (Stow’s) nose, ear and lip.”~~ Update 11:37 a.m.: Our LA Bureau Chief, Krissy Clark, says this language is actually part of the “mayhem” statute, and not reflective of actual injuries to Stow.

Here’s video of Friday’s LAPD press conference on the case, at which LA Police Chief Charlie Beck announced that Giovanni Ramirez, the original suspect who police had insisted was involved in the attack, was no longer under suspicion.

“In policing it is just as important to exonerate the innocent as it is to implicate the guilty,” Beck opened his remarks. “This is not just a phrase, these are words that define the character of the Los Angeles Police Department. Today we are here to announce the arrest of three suspects in the brutal beating of Bryan Stow. But just as importantly, I want to tell the world that Giovanni Ramirez is no longer a suspect in this case. The initial evidence and identifications which led to his arrest have been refuted by an investigation that has involved dozens of detectives working seven days a week over thousands of hours.”

LA Mayor Antonio Villaraigosa also spoke, defending the police investigation.
