AKIPRESS.COM - A former U.S. Marine combat veteran opened fire in a Los Angeles area bar packed with line-dancing college students, killing 12 people in a mass shooting that stunned a bucolic Southern California community with a reputation for safety, Reuters reports.

The gunman, identified by police as 28-year-old Ian David Long, was found dead of an apparently self-inflicted gunshot wound following the Wednesday night massacre at Borderline Bar and Grill in Thousand Oaks, a suburb 40 miles (64 km) northwest of downtown Los Angeles, law enforcement officials said.

Paul Delacourt, assistant director in charge of the Los Angeles FBI office, said it was too early to speculate on the shooter’s motives but that he appeared to have acted alone.
