thousand oaks shooting

Sgt. Ron Helus was struck by five bullets from the suspect's weapon. But it was a sixth shot, fired by another law enforcement officer, that proved fatal.

Not all the victims' names have not been released but among those confirmed are three men and a woman. They range from 18 to 33 — a reflection of the crowd drawn to the bar's "College Country Night."

Authorities have identified the gunman as Ian David Long, 28, a Marine Corps veteran. The Ventura County, Calif., sheriff says his office had a number of interactions with Long in recent years.

Sheriff's Sgt. Ron Helus had been speaking with his wife when reports of an active gunman came in. Within minutes, the veteran officer was on the hellish scene — but he would not survive the night.
