ROSEBERG, Oregon – Investigators on Saturday pieced together evidence on why a student at a college in Oregon went on a shooting rampage that left nine people dead before committing suicide as police cornered him.
Officials said the Oregon shooting gunman, identified as 26-year-old Chris Harper Mercer, was enrolled at Umpqua Community College in Roseburg, and opened fire in his English writing class.
Douglas County Sheriff John Hanlin said Mercer — whom he has refused to identify by name so as not to give him notoriety — exchanged fire with two officers who had rushed to the scene before committing suicide.
He said 14 weapons belonging to the perpetrator of the Oregon shooting had been recovered, including six found at the school along with a flak jacket and ammunition. Hanlin said investigators were poring through numerous leads and had interviewed hundreds of people, including neighbors and family members of the shooter, to try to determine what set off the rampage.
The Oregon shooting, the latest in a string of similar attacks in recent years at colleges and schools in the United States, has revived a fierce debate on gun control.
Officials say Mercer had struggled with mental health problems for some time and left behind a typed statement several pages long in which he indicated he felt lonely and was inspired by previous mass killings.
The shooter, who lived with his mother, also appeared obsessed with guns and religion and had leanings toward white supremacy.
It was unclear how long he had been a student at Umpqua, a small college of about 3,000 students located in Roseburg, a close-knit rural community.
The rampage took place on the fourth day of the new school year. Several students said Mercer had signed up for a theater class that had not yet started. Witnesses said he asked his victims their religion before shooting them execution-style.
Passionate about guns
Hanlin said investigators were examining how the shooter amassed his arsenal and were looking at some of his online postings.
Mercer moved from Los Angeles to Oregon with his mother in 2013, neighbors said, describing him as withdrawn and quiet but passionate when it came to guns.
“When we talked about guns and hunting, he was real open about it,”  Louie Flores, 32, a neighbor from California, told the New York Times. “But anything about what was going on in his life, he really didn’t say too much at all.”
In online postings linked to Mercer’s email address, investigators reportedly found one entry in which he expressed sympathy for a dismissed television reporter who killed two former colleagues during a live broadcast in Virginia in August.
In Roseburg, residents tried to come to terms with the tragedy and the sad reality that their town would now be remembered as the site of a mass killing.
The bodies of the nine victims — five women and four men aged between 18 and 67 — were handed back to their families on Friday.
Fire Marshall Greg Marlar said one of the victims, 20-year-old Treven Anspach, was the son of a local firefighter. Another rescuer lost his niece.
Nine other people were injured in the rampage, including one woman who was shot in the head, officials said.
Chris Mintz, 30, an army veteran, had tried to stop the bloodshed by charging Mercer but was shot seven times while pleading that it was his son’s sixth birthday. He survived.
The mass shooting reflects a grim reality of U.S. life, with similar incidents happening on a regular basis. The last mass shooting at a U.S. school took place in 2012 when 20 elementary school students and six adults were killed at Sandy Hook Elementary School in Connecticut.
According to data compiled by the group Everytown for Gun Safety, there have been 142 school shootings in the United States since the Sandy Hook massacre.
