‼️UPDATE: Suspect Identified in 1973 Murders of Teen Sisters in Florida Keys After More Than Five Decades

More than 53 years after two New Jersey sisters were murdered while vacationing in the Florida Keys, investigators have identified a deceased man as a suspect in their deaths.

Marguerite “Maggie” Jenkins, 18, and her 16-year-old sister, Mary Jenkins, were visiting the Florida Keys in April 1973. On May 2, the sisters were last seen hitchhiking on Stock Island.

The following day, May 3, a local resident discovered their bodies in a wooded area approximately 100 yards from U.S. Highway 1 near Mile Marker 99.5 in Key Largo. Both sisters had been severely beaten and had apparent gunshot wounds.

The investigation generated forensic evidence, but authorities were unable to identify a suspect at the time. The case remained unsolved for more than five decades.

A significant breakthrough came in 2018, when the Florida Department of Law Enforcement (FDLE) developed a partial male DNA profile from a bloodstain located on clothing belonging to one of the sisters. The profile was entered into the Combined DNA Index System (CODIS), but no match to a known individual was found.

Investigators continued to pursue new avenues as forensic technology advanced. In 2024, FDLE and the Monroe County Sheriff’s Office submitted evidence to Othram’s laboratory in Texas, where scientists used forensic genome sequencing to develop a more comprehensive DNA profile.

FDLE’s forensic genetic genealogy investigation subsequently produced a new lead pointing to David Allen Snyder.

Snyder had previously lived in the Key West area, including at several locations between 1972 and 1974. Investigators obtained a reference DNA sample from one of his relatives and compared it with the profile developed from the evidence in the Jenkins case. The testing supported the identification of Snyder as the individual associated with the DNA evidence, authorities said.

Snyder died in Idaho in October 2008. Because he is deceased, the identification comes more than 15 years after his death and more than 50 years after Maggie and Mary were killed.

The development does not erase the tragedy that has surrounded the Jenkins family for generations, but it provides a long-awaited answer in a case that had remained without a named suspect since 1973.

The investigation into the deaths of Marguerite “Maggie” Jenkins and Mary Jenkins demonstrates how evidence preserved from a decades-old crime can become the key to identifying a person of interest long after traditional investigative methods have been exhausted. Never ever give up hope.
