"A darker picture emerged Friday of slain Umpqua Community College shooter Chris Harper-Mercer as a deeply troubled, anti-religion, anti-government recluse obsessed with guns.
"The U.S. Army discharged him just five weeks into basic training in 2008. Records indicate he graduated in 2009 from a high school catering to troubled and special-needs students. Multiple media sources reported Friday he left behind an angry note that is now in the hands of investigators.
"The Los Angeles Times said Harper-Mercer's note was several pages long and talked about his anger and depression.
"Sofia Camarena of Long Beach, California, told The Oregonian/OregonLive that she used to date Harper-Mercer's father."I used to change Chris' diapers when he was a baby," she said, upset after learning that he was the shooter in Thursday's massacre and was himself dead. "He was born with problems. He was hard to discipline. If you told him 'no,' he would scream like you had just hit him."
"Camarena said that she had heard Harper-Mercer's mother was having "a hard time" with him and that he attended a special school.
"A neighbor told The New York Times that Harper-Mercer's mother had told a neighbor, "My son is dealing with some mental issues," and was intolerant of roaches that had infested the building.
"Witnesses said Harper-Mercer singled out the religious during the shooting. He reportedly asked students and staff their religion and shot those who answered they were Christians.
"The U.S. Army confirmed Friday it discharged Harper-Mercer just halfway through his 10 weeks of basic training in 2008. "A review of Army records indicate that Christopher Sean Harper-Mercer was in service at Ft. Jackson, S.C., from 5 November-11 December 2008 but discharged for failing to meet the minimum administrative standards to serve in the U.S. Army," said Lt. Col. Ben Garrett.
"Garrett declined to elaborate on what those "minimum administrative standards" were.
