Ian David Long and the 2018 Borderline Bar and Grill Massacre

Overview of the Mass Shooting

Ian David Long was responsible for the mass shooting at the Borderline Bar and Grill in Thousand Oaks, California, during the late evening of November 7, 2018. Long entered the crowded country-western bar and opened fire during its weekly College Country Night. He murdered 11 patrons and employees before exchanging gunfire with responding law-enforcement officers. Ventura County Sheriff's Sergeant Ron Helus was mortally wounded during the response, bringing the number of victims killed to 12. Long later died from a self-inflicted gunshot wound inside the building. The Borderline Bar and Grill was located at 99 Rolling Oaks Drive in Thousand Oaks, approximately 40 miles northwest of Los Angeles. College Country Night was especially popular among students from Pepperdine University, California Lutheran University, California State University Channel Islands, and Moorpark College. More than 200 patrons and employees were reportedly inside when the attack began shortly after 11:18 p.m.

Ian David Long's Background

Ian David Long was born on March 27, 1990, and lived with his mother in Newbury Park, a community within Thousand Oaks. He graduated from Newbury Park High School in 2008 and entered the United States Marine Corps that August. Long trained as a machine gunner, reached the rank of corporal, and served in Afghanistan from November 2010 until June 2011. He was honorably discharged from the Marine Corps in March 2013. After leaving the military, Long attended California State University, Northridge, where he studied athletic training but did not graduate. People who knew him described significant changes in his behavior following his military service. Investigators later documented evidence that he had experienced post-traumatic stress symptoms, anxiety, depression, chronic pain, anger, and difficulty adjusting to civilian life. These conditions, however, do not by themselves explain or excuse his decision to commit mass murder. Law-enforcement officers had previously encountered Long during disturbances. In April 2018, deputies responded to his home after reports that he was acting irrationally and aggressively. A mental-health crisis team evaluated him but determined that he did not meet the legal requirements for involuntary detention. No firearms were removed from the residence at that time.

Preparation and Weapons

Long armed himself with a legally purchased Glock 21SF semiautomatic pistol chambered in .45 caliber. Investigators determined that he carried multiple prohibited high-capacity magazines and approximately 190 rounds of ammunition. He also possessed a folding knife, smoke-producing devices, and fireworks. A tactical light and laser aiming device were attached to the handgun. Long wore dark clothing and drove his mother's vehicle to the Borderline Bar and Grill. Evidence gathered during the investigation indicated that he was familiar with the establishment and had previously visited it. His equipment, ammunition supply, and actions after entering the building demonstrated that the attack was deliberate rather than an impulsive confrontation. ...
