Summary based on the NamUs case record (MP28963) and 5 other sources
Mark Norman Dantche, 45, was last seen on May 30, 2015, in Calaveras County, California. He had called home at 9:30 p.m. from the Sheep Ranch Road area in Murphys, California. Mark was reportedly planning a fishing trip in the West Point area that day, and he was driving a blue 1996 Subaru Outback with a yellow kayak tied to the top. The vehicle had distinct characteristics, including a cracked windshield and a tied-down hood. Neither Mark nor his vehicle has been seen since that evening.

Dantche was described as being 5'8", weighing around 190 pounds, with gray hair and brown eyes. He had several distinguishing features, including burn scars on his right leg and a skin graft scar on his left thigh. He had suffered previous injuries, including a healed right foot fracture.

Extensive searches have been conducted by the Calaveras County Sheriff's Department, but no significant leads have surfaced. His disappearance remains a mystery, and the case is still open as authorities continue to seek information that could help locate him.
