At approximately 3 am on the 28th of this month, SanFire crews were notified of an incoming 911 call from a distressed member of the public. The person informed communication operators that they seriously injured and lost somewhere on Mount Chilliad. The SanFire communications office was able to ping the location of the injured person's phone to somewhere on the southern-side of the mountain, however an exact location could not be pin pointed. Eventually, 911 operators lost contact with the stranded person. Emergency service crews quickly rushed to the area and began an extensive land and air search. 2 helicopters were deployed and multiple cross-agency on-foot teams were deployed. Unfortunately, after several hours of unsuccessful searching, crews were unable to locate the missing person, and active searching was terminated. Passive searching with reduced resources continued over the next 24 hours.
