Vilan, who was on parole after spending six years in state prison for two assaults, had a lengthy history of ganging up on people and attacking them, according to court records. His convictions included two unprovoked assaults in 1996 and 1998, which involve Vilan smashing two people in the face with beer bottles.
In a 1996 attack, Vilan smashed a man in the face with a beer bottle, and continued to hold the broken bottle over his victim's face until the man's brother hit Vilan over the head with a wrench.
In the 1998 incident, Vilan, who was on bail at the time, approached a guest at a birthday party and sniffed him, saying, "You smell like white trash." The two men squared off, but before any punches could be thrown, Vilan smashed a beer bottle in the face of the man who stepped between them, court records show.
An October 2001 opinion by Court of Appeal, 4th Appellate District, also show a series of allged assaults for which Vilan was never charged, including a birthday party in August 1996 when Vilan and a friend were said to have brutally beat a guest who tried to stop them from ransacking the bedroom of the host's father, punching him and stomping on his head with steel-toed boots.
A month later, Vilan and two other men were accused of jumping the brother of one of Vilan's previous victims, punching him, knocking him to the ground and kicking him, court records show.
In November 1997, according to court accounts, Vilan and two other men attacked a man eating in his car with his girlfriend outside a fast-food restaurant, punching and kicking him.
Two months later, Vilan punched a man in the face three times just for looking at him, according to court records.
"None of the victims did any provoking – Vilan and his cohorts did all the provoking. All the victims were outnumbered. All the encounters featured 'low blows,' i.e., unfair fighting by Vilan and his cohorts," wrote Manuel A. Ramirez, presiding justice of the California Court of Appeal, 4rth Appellate District, in the October 2001 opinion rejecting Vilan's appeal that evidence admitted in his two trials was improperly admitted.
