Melissa Ann Northrup was 22 when she was abducted from her job at a convenience store in Waco, Texas, on March 1, 1992. She was a mother of two and was pregnant with her third child. Her body was found 51 days later in a gravel pit in southeast Dallas County with her hands tied behind her back.

Kenneth McDuff, who had previously been convicted in the 1966 murders of three teenagers and paroled in 1989 after his death sentence was commuted to life, was later linked to Northrup’s abduction and killing as part of a series of abductions and murders that followed his release. The case drew major criticism of the Texas parole system because McDuff had been free despite his violent history.

Anyone who knew Melissa, worked at that convenience store, or has information about her abduction is asked to come forward.
