New Details On Gunman

The Douglas County Sheriff's Office confirmed that 26-year-old Chris Harper Mercer was responsible for the carnage, but didn't refer to him by name so as to discourage future attention-seekers from committing violent acts. Sheriff John Hanlin said, "You will not hear anyone from this law enforcement operation use his name -- I believe that the media outlets who continue to use his name will only glorify his actions, and this will only encourage future shooters." He added that, "Oregon is a hunting state, and firearms are available in most households." Mercer's family informed police that he was dealing with mental health issues. Harper had a total of 13 firearms -- all legally obtained -- six of which were recovered at the school, with another seven at his home; and wore a jacket that had six magazines in it, officials said. While the incident which took place during a writing course on campus, investigators haven't found any evidence that tied him to the school as a student or otherwise.

Past Service

Mercer, who was born in the U.K. and raised in the states, was in the U.S. Army for just over a month in November of 2008, and discharged for "administrative reasons," officials said. The murderer, who was shot and killed by police to end the violent rampage, is not believed to have been affiliated to any groups.
