Summary based on the NamUs case record (MP1182) and 4 other sources
Terrence Arthur Diaz was last seen on November 14, 1999, in Palo Alto, California, at the age of 45. He is described as a white male, approximately 5 feet 10 inches tall and weighing around 180 pounds, with brown and gray hair that is thinning on top. His eyes are brown, and he has a distinctive feature: a missing tooth on the top right side of his mouth.

On the day of his disappearance, Terrence was reportedly wearing a t-shirt, a dark-colored sweater, a brown corduroy jacket, blue jeans, brown boots, and a brown cap. There are indications that he may have been living on the streets and might have played his guitar in public, as he was known to enjoy music.

Despite the time that has passed, his case remains unsolved, and the Palo Alto Police Department continues to seek information regarding his whereabouts. Anyone with relevant information is encouraged to reach out to the police department.
Last Seen: Nov 14, 1999
