Twelve people were killed after a Marine combat veteran opened fire during college night at a country music bar in Southern California.

Investigators are still working to identify all of the victims and notify their families. As more names are released publicly they will be added below.

Sgt. Ron Helus

Ventura County sheriff's Sgt. Ron Helus was shot late Wednesday when he entered the Borderline Bar and Grill in Thousand Oaks after reports of a shooting.

He is being described as a "cop's cop" that would take on some of the toughest assignments and was on the SWAT team, according to a friend, Sgt. Eric Buschow.

The Ventura County Sheriff said the report of the shooting came as Helus was on the phone with his wife. The sheriff said Helus told her, "Hey I gotta go handle a call. I love you. I'll talk to you later."

Cody Coffman

According to his father, 22-year-old Cody Coffman is among the 12 people who died in the shooting. Jason Coffman told reporters the last thing he told his son Cody was "I love you."

"I've been here fighting for him all morning long, and we did just get the news that he was one of the 11 killed last night. He was Cody Coffman, my first-born son," Jason Coffman tearfully described.

He added that Cody Coffman had dreams of joining the military and had been talking to Army recruiters.

Before authorities told him Cody was one of the victims Jason Coffman had said he was afraid his son "went toward the action" because he was the type of person who would stand up for others.
