Among the 13 dead after the shooting at Borderline Bar and Grill in Thousand Oaks was Ventura County Sheriff's Sgt. Ron Helus.
The 29-year veteran of the force entered the bar to confront the shooter, and sustained multiple wounds before he was pulled from the line of fire.
The 54-year-old father of one died from his wounds overnight.
A procession will take place at 10:00 am today to move his body, starting from Los Robles Hospital to westbound Janss Road.
From there, the motorcade will travel southbound on Lynn Road to US 101 northbound to the Ventura County Medical Examiner's Office.
There will be intermittent road closures in the area during that time period.
