On June 18, 1975, 14-year-old white female Barbara Susan Schreiber from Hollywood, Florida, was last seen with her best friend, 14-year-old white female Darlene Zetterower. The two girls had just completed eighth grade at Attucks Middle School and were looking forward to starting high school in the fall. That day, they left Barbara’s home intending to spend the night at another friend’s house, but they never arrived.
Witnesses later reported seeing the girls sitting on a bench along a busy street in Hollywood when a white van pulled up. The girls, known to occasionally hitchhike, appeared to enter the van willingly. The next morning, their bodies were discovered by a family on a fishing trip near Interstate 75 in the Florida Everglades, in an area known as Andytown. Both girls had been sexually assaulted and shot to death. Their bodies were found fully clothed and lying side by side on a dirt road.
The double homicide shocked the community and launched a decades-long investigation. Despite efforts by numerous detectives over the years, the case went cold. In recent years, however, advancements in DNA technology allowed investigators to extract a full DNA profile from evidence collected from the victims’ clothing. This led to the identification of a suspect: Robert Clark Keebler, a man with a criminal history that included armed robbery, sexual assault, and aggravated assault across California and South Florida. Keebler died several years before he was identified, and therefore could not be prosecuted.
Further investigation revealed that Keebler had not acted alone. In May 2025, authorities announced the identification of a second suspect: Lawrence Stein, another felon with a history of violent crimes. Stein had died in 2005. Although both suspects are deceased, the Broward County Sheriff’s Office confirmed that if they had been alive, they would have been prosecuted for the murders of 14-year-old white females Barbara Susan Schreiber and Darlene Zetterower.
The case is also believed to be potentially connected to the broader series of unsolved killings known as the Flat Tire Murders, which involved the deaths of multiple young women in South Florida between 1975 and 1976. However, investigators have not definitively linked Barbara and Darlene’s murders to that series. Authorities continue to seek information from the public that might shed further light on the events of June 1975.
