THOUSAND OAKS - A memorial service will be held Thursday for the Ventura County Sheriff's Office sergeant who was killed when he responded to a mass shooting Wednesday night at the Borderline Bar & Grill.

Services for Sgt. Ron Helus will begin at noon Thursday at Calvary Community Church, 5495 Via Rocas in Westlake Village.

Immediately after the memorial service, there will be a short procession and graveside service at Pierce Brothers Valley Oaks Mortuary and Cemetery, 5600 Lindero Canyon Road in Westlake Village. Parking will be limited and carpooling is suggested.

Helus was one of the first officers to arrive on the scene about 11:20 p.m. Wednesday after a hooded man entered the bar and began shooting. Helus was shot several times and died later at a hospital.

The 29-year veteran of the Ventura County Sheriff's Office was among 12 people killed by Ian David Long, 28, of Newbury Park. Long later died of a self-inflicted gunshot wound.

Helus is survived by his wife and son.

Meantime, the posts Long put on social media have been taken down.

Investigators wearing white hazmat-style suits and respirators over their faces continue to process the scene that Long left behind. That part of the investigation will continue at least through Tuesday, a Ventura County Sheriff's Department spokesman said.
