On the night of 4 April, 1991, 20-year-old Angela Marie Hammond called her fiancé, Rob Shafer, from a pay phone which was located in the parking lot of a grocery shop in Clinton, Missouri. The couple were awaiting the birth of their first child together and Angela had arranged to meet Rob that night. She called to tell him that she was too tired to meet and was going to head home and get a bath. While on the phone, Angela informed Rob that there was a man in a pickup truck circling the parking lot before parking his truck, getting out, and pretending to look for something. She gave Rob a description of the man before screaming and the line going dead. Rob jumped in his car and made his way to the parking lot. On the way, he passed a green Ford F-150 pickup truck and believes that he heard Angela screaming his name from the truck. He immediately turned his car around and took off after the truck for approximately a mile before his car went dead. Her abandoned car was discovered at the parking lot beside the pay phone but her body, and the man in the green truck, were never found.
