MARTINEZ -- An "all for one, one for all" mentality led a group of young gang members to kill a 16-year-old Oakley boy at an Antioch house party for high school students, a prosecutor told jurors Monday.
Leon Moreno, Ricky Mendoza and Tony Martin, all 20, are on trial on murder, attempted murder and gang charges in connection with the Aug. 20, 2011, shootings in which Martin Navarro was killed and a 17-year-old female party guest was wounded in the shoulder.
In opening statements Monday, Deputy District Attorney Danielle Douglas said Navarro was killed because the defendants believed him to be a rival gang member, but it was unclear why the teenage girl was shot.

Defense attorneys said there is no evidence that their clients were armed and forewarned jurors of conflicting evidence as to who was armed and inside the garage that night.
