Seven men -- all members of a San Jose gang -- have been found guilty of a 2007 stabbing murder, according to the San Jose Mercury News.
Two men -- David Ayala and Carlos Valdez, who were 16 and 17 when they repeatedly stabbed Adrian Medina, 19, and broke his skull with a baseball bat -- were found guilty of first-degree murder, the newspaper reported.
The five other members of Los Latinos Locos were found guilty of second-degree murder for their roles in the killing of Medina, who was jumped at a San Jose party "for no reason," the newspaper reported.
Medina was not in a gang.
He was stabbed 25 times by Ayala, the newspaper reported, an attack that pierced his heart and "eviscerat[ed]" him.
Witnesses including a woman who is related to one of the defendants participated with investigators in bringing the killers to justice, the newspaper reported.
All of the defendants -- whose $2 million in legal fees were paid for by county taxpayers -- face lifetime sentences in prison, the newspaper reported.
