A second high school coach of the gunman who killed 12 people at a Southern California bar recalled him as volatile and intimidating, and said that repeated complaints to school administrators about his behaviour failed to prompt any discipline. Evie Cluke coached Ian David Long on Newbury Park High School's track team in 2007 and 2008. In an interview with The Associated Press on Sunday, she said Long was a "ticking time bomb" who constantly lost his temper, threw tantrums and would scream at coaches when he didn't like their decisions. She said she once witnessed him assault a fellow coach. That coach, Dominique Colell, said Long grabbed her rear and midsection after she refused to return a cellphone.

Another time, he used his hand to mimic shooting her, Colell said, adding that she feared for herself whenever she was around him. Cluke said she also witnessed Long pretending to shoot Colell. "When Dominique turned around and saw that, she turned pale as a ghost and it was very, very scary." Cluke said. "Just sadistic. ... He was out of control. He would scream and cuss and his face would turn bright red and people would actually back away from him." Long, a 28-year-old former Marine machine-gunner who served in Afghanistan, opened fire during college night at the Borderline Bar and Grill in Thousand Oaks on Wednesday night. He killed 11 people and a police officer who responded, and then fatally shot himself, police said. Authorities have not determined a motive.
