He was described as 5 feet 10 inches tall, about 140 pounds, with brown hair and brown eyes, last seen wearing a light pink or white long-sleeved shirt, blue dress pants, and black tennis shoes. The case is classified as a lost or injured person and remains an open investigation with the Maricopa County Sheriff’s Office; his information has been entered into national missing-person databases.
