Summary based on the NamUs case record (MP7541) and 6 other sources
Robert H. Houk, age 26, was last seen on October 1, 1990, in Indianapolis, Indiana. He was walking away from his father's residence around noon, carrying a pair of cowboy boots and two pairs of pants slung over his shoulder. At the time of his disappearance, Robert did not have access to a vehicle and was known to hitchhike. He was last seen wearing blue jeans, a blue jacket, and cowboy boots. Robert had distinctive physical features, including a deformed middle finger on his right hand, pockmarks on his face, and a surgical scar on his left knee. He also may have had a beard and used the nicknames "Bobby" and "Cowboy Bob."

Robert had a history of using tranquilizers and was reported to have violent tendencies, leading to concerns for his safety. Despite his disappearance being handled by both Indiana and Palm Beach County, Florida authorities (where he had previously lived), no significant leads have surfaced. In 2008, Robert was declared legally dead, though his case remains unsolved, with investigators continuing to seek information.

If anyone has details about Robert’s case, they are encouraged to contact the Palm Beach County Sheriff's Office, which continues to oversee the investigation.
