Michael Andrew Riley, 22, disappeared after a night out at The Vogue Theater nightclub in Indianapolis on May 28, 1983. Witnesses later reported he left the club with a man who was not identified at the time.

On June 5, 1983 a resident looking over a bridge in Blue River Township, Hancock County, found a partially submerged, nude body in the creek. The remains were identified as Riley’s and an autopsy determined the cause of death was ligature strangulation. Investigators later saw Riley’s killing as part of a pattern: several young men last seen in Indianapolis gay bars were recovered in rural locations, and police linked his death to at least nine similar murders in the region.

A lead emerged in February 1998 when a local resident identified the man who had been seen leaving the Vogue with Riley as Herb Baumeister, a businessman who by then was deceased. Baumeister became the primary suspect in this unsolved homicide and in the series called the I-70 Strangler, though he was never charged in Riley’s death.

Did anyone who knew Riley or frequented the Vogue Theater in 1983 ever see him with that man or remember details about that night?
