Summary based on the NamUs case record (MP82827)
Mark Aaron Kilner, aged 46, was last heard from on April 16, 2012, in North San Juan, California. Concern arose when his family, who lived out of town, hadn't heard from him for some time. A friend visited his residence for a welfare check and found his wallet and car keys still in the home. However, Kilner was missing. An extensive search and rescue operation was launched in May 2012, but no trace of him has ever been found.

Kilner was described as a 5'11" tall Caucasian male, weighing around 165 pounds, with brown hair and blue eyes. Despite significant efforts to locate him, the circumstances surrounding his disappearance remain unclear. His case remains unsolved, and authorities continue to seek any information that could lead to answers.
