In 1992, ABC News ran a story covering the mystery, digging into whether the case was a suicide or a murder. This same year, Keith's mother received a manila envelope with crime-scene photographs and noticed that the clothing her son was wearing at the time of death did not fit him properly—it was not his own clothing, and he was not wearing his own shoes. The only items the police returned to her were Keith's jacket and brown boots, neither of which were in the photographs she received. At this time, she hired a private investigator. The investigator noticed that in the photographs, the jacket was covered in leaves and dirt, appearing as if Keith were dragged into the air rather than hanging himself.
