Ronnie Leo Bromenschenkel, 26, was last seen August 6, 1986, at the Riverview Trailer Court in St. Cloud, Minnesota. He vanished the same day as his girlfriend, Cynthia Mae Schmidt, 18. Authorities say the couple had been involved in a money laundering scheme before their disappearance, a circumstance investigators believe may have been a factor.

Bromenschenkel is described as a white male with brown hair and brown eyes, standing between 5 feet 8 inches and 6 feet 4 inches and weighing about 165 pounds. He reportedly had several tattoos on his arms, legs and abdomen and scars on his abdomen, left arm and knee. Investigators strongly suspect foul play and both are presumed deceased, but no bodies have been found and the case remains unsolved and classified as endangered missing.

Anyone with information about where Ronnie or Cynthia might have gone on or after August 6, 1986, is asked to contact the St. Cloud Police Department.
