Summary based on 1 source
In the autumn of 1993, a sense of quiet concern settled over a family who had not had contact with 28-year-old Robert William Dikes in several years. Known as 'Robby' to his loved ones, he was a tall man, standing at 6 feet 4 inches with a slender build, blond hair, and hazel eyes. The last confirmed sighting of Robert was in Phoenix, Arizona, on September 25, 1993. On that day, he had an interaction with the Phoenix Police Department, though the specific nature of this contact has not been publicly disclosed. This interaction marks the last known time anyone has officially reported seeing him.

The years leading up to Robert's disappearance are marked by a lack of detailed public information, which adds to the mystery of his case. His family's last contact with him was three years prior, in 1990, when he was in San Diego, California. The reasons for the gap in communication and his move to Phoenix are not widely known. The investigation into his disappearance is being handled by the San Diego Police Department, despite him being last seen in Phoenix. This detail suggests that his ties to San Diego were considered significant in understanding his life and the potential circumstances of his disappearance.

Decades have passed since Robert William Dikes was last seen, and his case remains unsolved, leaving his family with unanswered questions. There is no public information available regarding the clothes he was wearing on the day he vanished, nor is it known if he had access to a vehicle. The scarcity of information has made the investigation challenging. Over the years, unconfirmed online discussions have mentioned the possibility of his body having been discovered in July of 1993, prior to his official last seen date, but this has not been substantiated by law enforcement. The overview of the case is one of limited facts and a lingering sense of uncertainty, a painful reality for a family still waiting for answers about what happened to Robby.

Last Seen: Sep 25, 1993
