Over 100 fire and safety personnel continued their search Sunday for 36 year-0ld Mike Herdman, an Arcadia firefighter who went missing in Los Padres National Forest during a camping trip on June 13. 

Herdman was camping with a friend when he rushed off into the surrounding woods after his dog in without shoes or equipment. He hasn't been seen since. 

Update 2:24 p.m.: Search crews find missing firefighter's dog

Search crews looking for a missing Arcadia Fire Department say they've found the dog he went after when he left his camp ground, shoeless and without his gear. They still haven't located Herdman himself, however. 

The Arcadia Fire Department's union posted a photo of the dog, named Duke, on their Facebook page Sunday afternoon.

Update 10:39 a.m.: Crews, drones continue search for missing firefighter Mike Herdman

Ventura County Sheriffs Captain Don Aguilar told KPCC the search crews, comprised of personnel from Orange County, Kern County, L.A. County, the Department of Homeland Security and elsewhere -- are combing a 6 mile stretch where they spotted Herdman's dog on Thursday. Though they weren't able to catch him, crews hope the dog will lead them to Herdman. 

Aguilar said search teams believe they heard the dog barking Friday night close to where they'd spotted him earlier. 

Two aerial drones — one from the Ventura County Sheriff's Department, and another from Simi Valley-based AeroVironment are being used to scour the area from above. 

"This is the first time we've used [the drones] in our history for an operation and a rescue search operation," Aguilar said. "We've been testing with this over the past year [...] And this is exactly what we wanted to use it for — a search and rescue operation."

The FAA issued a temporary emergency permit for the sheriff's department to use their drone in the area, Aguilar said. 

ABC7 reports five people have been injured in the search, including Assistant Fillmore fire chief Bill Herrera, who remains in intensive care for a rattlesnake bite on his hand.
