Summary based on the NamUs case record (MP12550) and 4 other sources
Patrick James Pfeiffer, 56, was last seen in Altadena, California, on July 21, 2011. After an argument with his wife, Pfeiffer left his home at approximately 1:00 a.m. He drove his vehicle to a friend’s house, where he left the car along with a note requesting that it be returned to his wife. Pfeiffer has not been heard from since, and his case remains unsolved.

Pfeiffer was suffering from depression at the time of his disappearance. He is described as a Caucasian male with blue eyes, standing 5'9" tall and weighing about 190 pounds. He has several distinctive scars, including surgical scars on his right shoulder and both knees, as well as a pin and scars on his lower right leg. He also wears partial dentures and glasses.

Authorities have continued to seek leads in the years following his disappearance, but few details have emerged. The Los Angeles County Sheriff's Department is handling the investigation.
