A mass shooting in California leaves 12 people dead and the shooter is a former Marine with Hawaii ties.

Police continue to investigate what happened and piece together the details of this horrific incident.

The motive is still unknown. The bar that hosted College Country Night includes at least 16 students from Pepperdine University. 

One former Hawaii resident who recently moved to Thousand Oaks, works at Pepperdine University where another vigil was held Thursday afternoon.

"Our student was actually killed. She was a freshman. It was just horrible. Everyone today. All of the staff members, faculty, students were all just, it was an eerie feeling. Just really sad," Brianna Lovett, former Hawaii resident, said. 

That freshman is 18- year-old Alaina Housley. Lovett says Thousand Oaks is one of the safest neighborhoods, she says this mass shooting is a huge surprise.

Multiple other vigils were held in Thousand Oaks as hundreds of community members gathered together to mourn and show their support. 

The community is also dealing with two brush fires that exploded in Ventura County this afternoon that shut down part of the 101 Freeway, which is a major freeway in California, as firefighters rushed to get the flames under control.

The larger fire was burning in the Santa Rosa, just mere miles from the scene of this deadly mass shooting that claimed 12 lives Wednesday night.

Fire officials estimated the size of the blaze at close to 10,000 acres.
