Ian David Long and the 2018 Thousand Oaks Mass Shooting

Overview

On the night of November 7, 2018, 28-year-old Marine Corps veteran Ian David Long carried out a mass shooting at the Borderline Bar & Grill in Thousand Oaks, California, during a popular College Country Night. He killed 12 people—including Ventura County Sheriff’s Sgt. Ron Helus—before dying by suicide inside the bar. Authorities and subsequent investigations documented that Long fired 61 rounds as approximately 260 patrons and staff tried to flee or hide.

Timeline of the Attack

At approximately 11:18 p.m. PST, Long entered the Borderline through the front door and immediately began shooting, first striking the cashier area and then patrons on the dance floor. Within minutes, California Highway Patrol officers and Sgt. Helus approached the entrance. Long, watching their movement on the bar’s internal camera monitor from the front office, ambushed them; Sgt. Helus was struck multiple times by Long and fatally by a round inadvertently fired by a CHP officer during the exchange. Long ceased attacking after the gunfight, deployed small pyrotechnics, and at about 11:38 p.m. died by a self-inflicted gunshot. Nineteen survivors were rescued from inside once police re-entered. The Ventura County District Attorney’s detailed report further confirms these timings, the ambush from the office doorway (roughly 7–14 feet), the friendly-fire wound to Sgt. Helus’s heart, and that Long had 129 rounds remaining when he died.

Weapons, Ammunition, and Tactics

Investigators recovered Long’s .45-caliber Glock 21 pistol with a 26-round high-capacity magazine inserted, seven additional high-capacity magazines (several loaded with 23–24 rounds), a folding knife, roughly 190 rounds in total, and multiple smoke-generating devices used to fill the venue with thick smoke. Witness accounts of smoke were corroborated by the official findings. Contemporaneous analyses noted the model and configuration of the handgun (Glock 21, .45 ACP) and the use of illegal extended magazines under California law. ...Read More
