Ronald Emmitt Yocom, 67, of Running Springs, California, was last seen June 3, 2018, while hiking near Hunsaker Road and Deep Creek. He was in the early stages of dementia and had heart disease; his daughter reported him missing four days later after she hadn’t heard from him.

Yocom was last seen wearing a black t-shirt and blue overalls. He is described as a Caucasian male with gray hair and brown eyes, 5 feet 9 inches tall and weighing between 200 and 235 pounds. Searches of the hiking trail turned up no signs of him, and investigators say no further leads have emerged.

If anyone hiking that area around June 3, 2018, remembers seeing a man matching Ronald Yocom’s description or has any information, please come forward to help his family.
