Donna Emmel was last seen on June 16, 1975, spending the day at the America Service Station and Grill, also known as Grice’s Grill. Her mother phoned the store that evening and was told Donna had already left. Witness statements, including one from her younger brother, placed Donna at the trail entrance leading into a wooded area while being followed by an unidentified man. Her body was discovered the next evening, June 17, 1975, in a drainage ditch across from the family home.

The timeline from the trail entrance to the location where Donna’s body was found is a key gap in the case. Any details about the unidentified man, his appearance, direction of travel, or whether anyone else saw Donna after she left the grill could be crucial. If anyone knew Donna’s routines that summer or remembers seeing her near that trail on June 16, 1975, contact the investigators handling the case with what they remember.
