Authorities search for gunman’s motive in mass shooting, believe there is no ongoing threat to Los Angeles area

THOUSAND OAKS, Calif. — Authorities are investigating a shooting during college night at a country music bar in Southern California, that killed 12 people and sent hundreds fleeing in panic.

The shooting occurred Wednesday night at the Borderline Bar & Grill in Thousand Oaks, California.  At least 12 people were killed. Multiple people were hurt and taken to area hospitals.

Prior to the presser, authorities had identified the gunman as 28-year-old Ian David Long.  Long is accused of bursting into the packed bar and opening fire on people dancing. Long was reportedly a former Marine and a decorated combat veteran.

Authorities found Long dead inside an office adjacent to the bar’s entryway.

According to a Thursday afternoon press conference the families of the victims have been notified of the tragedy. The Ventura County Sheriff's Office says their names should be released in a few hours.

Officials say they cannot release the cause of death until after completion of the autopsies.

The Los Angeles FBI Response team is reportedly processing the scene at the Borderline Bar & Grill, as well as searching the suspect's home and car for evidence.  The FBI says they are still working to paint a picture of the suspect's mindset and identify a motive.

The FBI says the LA response team will be substituted by response teams from other areas.  They will also pursue the suspect's digital trail and any other leads presented to them.  They are also requesting video taken by witnesses on or near the scene during the shooting and area surveillance video.

According to officials, AIF is working with local and state officials to keep the area safe.  They say they will continue to help until the community is safe.

Additionally, the FBI says they are working to provide mental health services to those who were impacted by the tragedy.

Officials say the investigation is developing.  There are reportedly no indicators of threats to the Los Angeles area or any indicators that the shooter worked with an associate.

CSI analysis will be ongoing for several days, however officials say it is premature to release an official timeline for the investigation.

This is an ongoing investigation. FOX 8 will provide more information as it becomes available.
