Borderline Bar & Grill

Since the mass shooting at the Borderline Bar & Grill in Thousand Oaks, Calif., last month, there's been more than 70 events - memorials, vigils and fundraisers — for the families of the victims.

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.
