Otto Gary Becker, 41, was found dead in a ditch alongside a gravel road in a rural, southwestern part of Henry County, Indiana, not far from Greensboro on August 7, 1991. Investigators treated the death as suspicious and evidence pointed to foul play.

Witnesses placed Becker earlier that day in his brown 1982 Honda Accord on Interstate 465 near Shadeland Avenue in Indianapolis. Those witnesses reported Becker was not in control of the situation — one white male was restraining him while another white male drove — and his car was later located abandoned in Columbus, Ohio. Becker was known to frequent homeless shelters and motels on Indianapolis’s east side.

Decades later, investigators linked Becker’s killing to a series of bodies found along the I-70 corridor attributed to a suspected serial offender called the I-70 Strangler. Herbert Baumeister was considered a possible suspect in those I-70 cases; he died by suicide before he was interviewed about Becker’s death and was never charged in Becker’s case. Otto Becker’s murder remains unsolved.

Did anyone who knew Becker or saw his brown 1982 Honda Accord that August have information that hasn’t been shared with investigators?
