A gunman opened fire late Thursday night in a Southern California bar and country music venue. The Ventura County sheriff said the bar was crowded with more than 100 people, many of them college students during the bar's weekly "college night."
The gunman, identified by police as Ian David Long, 28, killed 12 people, including a sheriff's sergeant who responded to the gunfire. Police later found the shooter dead inside the bar, possibly from a self-inflicted wound.
The rampage took place at the Borderline Bar and Grill in Thousand Oaks, about 40 miles northwest of Los Angeles.
Authorities don't yet know the motive for the shooting.
"There was just young people, like young, 18, 19, 20, just having a great time," said a stepfather who was at the bar with his stepson. "And this maniac came in and started shooting at people for no reason at all."
