A Santa Rosa man who served time for his role in a high-profile 2006 slaying in a downtown parking garage is back in jail on charges he assaulted two people outside a nightclub less than a block away.

Raul Lopez-Granados, 25, was sentenced to five years in prison for being an accessory to the killing of construction worker Matthew Toste, 32, inside the Seventh Street parking garage.

He was on parole June 23 when he got into a fight with two men across the street from the Chrome Lotus nightclub on Mendocino Avenue, prosecutors said. He yelled gang slogans and knocked out one of the victims, prosecutor Karina Kowler said.

Lopez-Granados fled but was arrested Thursday after a police investigation, she said. He made his first court appearance Monday.

He is charged with two counts of felony assault and gang participation. He is expected to return to court Tuesday to enter a plea.

Toste was shot to death more than six years ago as he walked to another downtown nightclub, Seven Ultralounge, with two women. Prosecutors said he was confronted by Lopez-Granados and four other men. Joseph Kenneth Lopez Jr. was convicted of pulling the trigger and sentenced to life in prison.

The slaying led to widespread community discussions about gangs and downtown safety.
