At 11:18p.m., a gunman, later identified as Ian David Long, entered the Borderline Bar and Grill and opened fire on the approximately 260 patrons and employees inside. At the time, the bar was hosting a regularly scheduled
College Country Night event, which was popular among students in the area, especially those from
Pepperdine University,
California Lutheran University,
California State University Channel Islands, and
Moorpark College. carrying a total of 190 rounds, along with a folding knife, ten
smoke bombs, and two
fireworks. Upon entering through the bar's front door, Long first killed the cashier nearby, then started shooting at the patrons. Many of the victims died in the first few minutes of the shooting while they were lying on the floor or trying to charge at Long. At 11:19p.m., two
California Highway Patrol (CHP) officers on a traffic stop nearby were alerted to the shooting by people who had managed to escape. They arrived at the bar's parking lot a minute later and were joined by
Ventura County Sheriff's Sgt. Ron Helus four minutes after that. The three officers ventured towards the building, with Helus and one of the CHP officers entering at 11:25p.m. A minute later, they came under fire from Long, who had been monitoring their movements through the nine security cameras visible on a monitor in the front office where he had been taking shelter. In the ensuing gunfight, Helus was shot five times by Long, who used a flashlight with a laser sight on his pistol in the large, darkened, smoke-filled room. Positioned between Long and the CHP officer, Helus was also accidentally struck by a bullet from the officer's rifle that went through his heart and fatally wounded him. Initially there was confusion and miscommunication as to whether there was an officer down. Responding Ventura County Sheriff's deputies, who were securing the perimeter, located and evacuated Helus outside the building 20 minutes after he had been shot. A
SWAT team and other police officers arrived on the scene shortly afterwards. Agents from the
Federal Bureau of Investigation, the
Bureau of Alcohol, Tobacco, Firearms and Explosives, and the
Department of Homeland Security were deployed to further investigate the scene along with
EMTs and
paramedics from the
Ventura County Fire Department and
AMR to assist victims. Nineteen survivors were rescued from inside the bar in total. == Victims ==
