Emergency staff awaiting arrival of the coroner at an incident Wednesday in Humber Park.

About 2 p.m. Wednesday, Sept. 6, Cal Fire and Riverside County firefighters responded to reports of an injured hiker at Humber Park.

After hiking to the location, firefighters found one male victim, Jonathan Zuniga, 24, of Oceanside, who perished at the scene.

Firefighters then found a second severely injured male victim. Responders called for air support and Cal Fire Copter 901 performed a hoist operation. This person was delivered to an awaiting air ambulance at the U.S. Forest Service’s Keenwild Ranger Station, from where he was transported to an area hospital with serious injuries.

According to a Go Fund Me page for Zuniga’s family, the deceased’s brother, Nathaniel Zuniga, was the injured hiker.

The Riverside County Sheriff’s Department press release states that the results of its investigation indicate Jonathan and his brother fell while rock climbing, although other online comments believe they were trapped in a rockslide.

Also, according to the Go Fund Me site, Jon, who was active duty in the Navy, is survived by his wife Leah, a son Trevor and a little girl due in late January. Trevor also has a rare chromosome condition that requires special needs for which Leah remains a stay-at-home mom to provide the best care possible for him.
