Breaking News: Shooting at Borderline Bar in Thousand Oaks, California

​A gunman killed 12 people, including a sheriff's deputy, late Wednesday night when he opened fire on revelers in the Borderline Bar and Grill, a popular venue with college students for dancing in the suburb of Thousand Oaks, California. Here's what we know, according to various news reports:

  • The gunman was identified as Ian David Long, a 28-year-old veteran of the U.S. Marine Corps who had previous run-ins with the law.

  • The gunman was dressed in black and wearing glasses. He walked up to the Borderline Bar & Grill and shot a security guard standing outside. He then entered the bar, turned right and shot other security guards and employees.

  • Sgt. Ron Helus was shot several times and killed during an exchange of gunfire with the gunman. Helus and a California Highway Patrol officer were the first to arrive at the bar and went inside just before 11:30 p.m. PT.

  • The gunman was armed with a Glock .45 handgun, purchased legally, and some type of smoke device.  The gun usually holds 10 rounds, but the gunman used an extended magazine in this shooting.

  • The shooter's motive is unclear, as is any possible connection between Long and the Borderline bar.

  • Police had several contacts with Long previously. In April, officers responded to a disturbance at Long's home. Long was somewhat irate and acting irrationally. A mental health specialist met with him and ultimately decided not to detain him.​

  • The gunman was on active duty with the Marine Corps from August 2008 to March 2013.

  •  It was the fourth shooting in the United States in two weeks. The attacks include the death of two women at a yoga class in Tallahassee, Florida, and two shoppers gunned down in the parking lot and inside a Kroger in Jefferson, Kentucky. Twelve days ago, a gunman killed 11 worshippers at a synagogue in Pittsburgh.​

  • President Trump on Thursday ordered flags to be flown at half-staff in remembrance of the 12 people.
