Steven Isles was 33 when his body was found on the side of Jackson Road in Monroe Township on Friday, October 26, 1990. He was from Williamstown, New Jersey. Investigators determined he had been shot multiple times and that the fatal wounds were inflicted at a secondary location; his body was later transported and left at the roadside where it was discovered.

The investigation has remained active over the years but has produced no arrests and no publicly identified suspects. Authorities have pursued leads and sought help from the public, yet the case has grown cold and the motive and circumstances behind Isles’s killing remain unresolved.
