Summary based on the NamUs case record (MP9038) and 4 other sources
On a summer afternoon in Phoenix, Arizona, 44-year-old Ronald Chris Peterson was last seen leaving his residence. It was approximately 1:00 p.m. on July 23, 1994, when he departed from his home located in the area of North 89th Avenue and West Thomas Road. Known as Ron to his friends and family, he has not been seen or heard from since that day. At the time of his disappearance, Peterson was described as a white male with blond or strawberry-blond hair, blue eyes, and a mustache. He stood between 5'6' and 5'10' tall and weighed between 190 and 200 pounds. He has a scar on his abdomen below his navel. When he was last seen, he was wearing a large blue shirt, blue jeans with a 34-inch waist and a 29 or 30-inch length, and size 11 white sneakers.

The circumstances surrounding Ronald Peterson's disappearance remain unsettling and with few available details. A significant and troubling discovery was made when his vehicle, a white 1986 Toyota Camry with Arizona license plate DLS774, was found abandoned. The car was located in a desert area south of 91st Avenue and West Baseline Road, unoccupied. This discovery only deepened the mystery of his whereabouts, leaving his family and investigators with more questions than answers. The Phoenix Police Department opened an investigation into his case two days after he was last seen.

The case of Ronald Peterson is a long-standing and painful mystery for his loved ones and the Phoenix community. Over the years, his case has been classified as an endangered missing person, and despite the passage of time, it remains unsolved. The lack of significant leads has made it a challenging case for the Phoenix Police Department. His family has endured decades of uncertainty, hoping for answers and a resolution. The overview of the case highlights a man who vanished from his home, his car later discovered in a desolate desert area, with no further trace or communication. The absence of any new information has left his disappearance a lingering and sorrowful cold case.
