James Boyd Robbins was 21 when he disappeared from Indianapolis the night of October 15, 1987. He was last seen about 10 p.m. after leaving his mother’s home and heading toward the southern part of the city. Two days later, on October 17, his naked body was found in a ditch in rural Shelby County near Interstate 70 south of Glennville; he had been strangled.

Witness accounts about a vehicle near the crime scene conflicted, with one person describing a red Jeep Wrangler Renegade and another describing a Chevrolet Blazer. Robbins’s killing has been linked to a series of similar murders along Interstate 70 attributed to an unidentified offender dubbed the I-70 Strangler; at least eleven young men and boys were killed in Indiana and Ohio between June 1980 and October 1991, with bodies often left near I-70. Investigators later identified Herb Baumeister as a prime suspect in April 1999.

Does anyone have memories, tips, or information about James’s movements in Indianapolis on October 15, 1987, or about vehicles seen near I-70 that week?
