The motive behind Wednesday night's mass shooting at a country music bar in California is still a mystery, but a picture is emerging of a gunman who was deeply troubled even before he served as a Marine in Afghanistan. Dominique Colell, a track coach at Newbury Park High School in Thousand Oaks, tells CBS Los Angeles that Ian David Long attacked her during his senior year. She says the assault happened after someone gave her a phone they had found during practice. "Ian came up and started screaming at me that was his phone," Colell says. "He just started grabbing me. He groped my stomach. He groped my butt. I pushed him off me and said after that—'you're off the team,'" she says.
