Sandra Jackson was a 21‑year‑old Black woman from Miami who was found dead on April 16, 1989. She and 20‑year‑old Hispanic Brenda Hernandez had been seen together the night of their deaths with Miami man Charles Henry Williams. Williams was arrested in April 1989 after being seen in their company and initially charged with rape.

Authorities said Williams had an extensive record of sexual‑assault arrests, including at least five jailings between May 1987 and March 1989. He was later indicted in a 1984 rape‑homicide and was linked by investigators to other cases; the medical examiner determined Sharmanita Grays and at least 13 other victims had been asphyxiated, a pattern that drew investigators’ attention.

Did anyone who knew Sandra or Brenda see them with Charles Williams that night or have other information about their movements?
