Umpqua Community College shooting

He expressed admiration for the misogynist mass killer responsible for the 2014 Isla Vista killings.

According to the Anti-Defamation League (ADL), "The issue most often raised about the shootings is whether they constitute an anti-Christian or anti-religious hate crime."

By some accounts, the shooter asked his victims about their religion before killing them, but others point out that his rage was not limited to religious matters and stressed his mental health history.

The report that the shooter asked victims about their religion before killing them comes from a survivor, as well as family members of the victims.

Following the shooting, Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) agents launched a campus-wide search for explosives.

Six firearms were recovered from the crime scene: five handguns and one long gun.

None were owned by his mother.

The long gun, a 5.56 x45 mm Del-Ton DTI-15 semi-automatic rifle, was not used during the incident.

Harper-Mercer also had a flak jacket and "enough ammunition for a prolonged gunfight".

Police said they found eight other firearms at his apartment, and that all of the weapons were purchased legally by him or members of his family.

The Umpqua Community College shooting occurred on October 1, 2015, at the UCC campus near Roseburg, Oregon, United States.

Chris Harper-Mercer, a 26-year-old student who was enrolled at the school, fatally shot an assistant professor and eight students in a classroom, and injured eight others.

Roseburg police detectives responded to the incident and engaged Harper-Mercer in a brief shootout.

After being wounded, he committed suicide by shooting himself in the head.

The mass shooting is the deadliest in Oregon's modern history.

At 10:38 a.m. PDT, the first 9-1-1 call was made from Snyder Hall on the school campus reporting gunfire.

Students reported that the shooting began in Classroom 15, where English and writing classes are conducted.

Harper-Mercer, who was a student in the writing class, entered the hallway and fired a warning shot.

Some witnesses said he then forced fellow students to the center of the classroom.

Before he opened fire on the other students, he deliberately spared one student's life so that the student could deliver a package from him to the police.

He forced this student to sit at the back of the classroom and watch as he continued shooting with two handguns (Glock 19 and Taurus PT24/7).

Harper-Mercer first shot the English professor at point-blank range.

One student said that he asked two victims for their religion, although their responses did not appear to determine who he shot.

One victim was agnostic and another was pagan.

Some students were shot multiple times; one woman was struck several times in the stomach while trying to close a classroom door.

One witness said he made a woman beg for her life before shooting her, shot another woman when she tried to reason with him, and shot a third woman in the leg after she tried to defend herself with a desk.

One victim, Sarena Dawn Moore, was killed while trying to climb back into a wheelchair on his orders.

Roseburg Police Sergeant Joe Kaney and Detective Todd Spingath (who were plainclothes at the time of the shooting) were the first to respond to the scene.

They arrived at the hallway of Snyder Hall at 10:44, six minutes after the first 9-1-1 call was received.

Two minutes later, Harper-Mercer reloaded his handguns and leaned out of the classroom, firing several shots at the officers.

They fired three shots in return, hitting him once in the right side.

After two more minutes of shooting at the officers, the wounded Harper-Mercer retreated into the classroom and killed himself with a single shot to his head.

None of the officers were injured.

Kaney is a U.S. Marine Corps veteran with 23 years on the Roseburg Police Department while Spingath is a U.S. Air Force veteran with 16 years on the Roseburg Police Department.

The package that Harper-Mercer had given to a student during the attack contained writing in which the shooter stated his motivations.

Harper-Mercer complained that he had "no friends, no job, no girlfriend" and was a virgin.

He critiqued other mass killers.

Harper-Mercer used language associated with the incel subculture.

Almost four hours after the shooting, Laurel Mercer was interviewed by Oregon State Police detectives, but the content was not released until September 13, 2017.

She said her son had been prescribed medication, but it did not seem to help, and that he had been "born angry."
