Ronald Allen Vonderheide was 23 when he disappeared from Cincinnati, Ohio, in the spring of 1987 after an argument with his mother at the family home on the 6200 block of Cambridge Avenue. He reportedly left the residence and was never heard from again. It was said that Ron sometimes went days without contact, but he had never before been missing for such a long time.

At the time he vanished he was described as a white male, 5 feet 10 inches, 160–185 pounds, with light brown hair and blue eyes. Distinguishing marks included a previously fractured ankle, a missing crown on his upper left front tooth, quarter-sized scars on his back and the back of his upper left arm from a prior gunshot, and a bullet lodged in his ribcage. He was last seen wearing a t-shirt, shorts and sneakers. Reports note inhalant abuse and other mental health issues.

The case is now cold. The Miami Township Police Department remains the investigating agency; DNA from his mother and brother has been entered into national databases for comparison to unidentified remains. No trace of him has been found and the disappearance remains unsolved.

Did anyone in the Cincinnati area remember Ronald or see him around Cambridge Avenue in spring 1987?
