On August 1, 1974, six-year-old Mylette Anderson and her eleven-year-old sister, Lillian "Annette" Anderson, vanished from their home in Jacksonville, Florida, under mysterious circumstances. Their mother and older sister had left them alone around 6 p.m. to visit a sick relative, and everything seemed normal during a 7 p.m. phone call between their mother and the girls. However, by 7:20 p.m., when their father returned home, the girls were missing.
Their disappearance was immediate and baffling—neighbors reported seeing a white car in the driveway, but there were no signs of struggle. The family dog, which was usually free in the house, had been shut in a bedroom, and Mylette’s favorite doll was also gone.
The Anderson sisters' disappearance was part of a troubling series of cases that gripped Jacksonville that summer, with five girls disappearing in just three months. While two of those missing girls were later found deceased, the bodies of Mylette and Annette were never recovered. Speculation initially pointed to serial killer Paul John Knowles, who claimed responsibility for the deaths of two girls fitting the sisters’ descriptions. However, despite his confession, authorities could find no physical evidence linking him to the crime, and his involvement remains uncertain. Over the decades, the case has gone cold, with no solid leads emerging, leaving the fate of the two young sisters unresolved. Their parents passed away without ever learning what happened to their daughters.Last Seen: Aug 1, 1974
