Cassandra Johnson was 20 when her partially clothed body was found in a wooded area near West Georgia Road in Simpsonville, South Carolina on September 22, 1984. A college student studying political science at Johnson C. Smith University and the mother of a three-year-old daughter, she had been last seen the night before speaking with a neighbor outside her family’s apartment. An autopsy found she had been stabbed multiple times.

The Simpsonville Police Department opened a homicide investigation that produced several persons of interest over the years but no arrests. In 1997 a former Simpsonville investigator destroyed evidence collected in the case, a loss that investigators say severely hampered later efforts to apply newer forensic methods. The case remains open and cold, and Cassandra’s family continues to seek answers.

If anyone knew Cassandra, her movements that weekend, or has information that could help, please come forward.
