Diana Lynn Valleck was 18 when her body was found on May 19, 1975, in an orange grove in Pasco County, Florida. She had been shot in the head 22 times. Her body was discovered less than three miles from where Wilma Ida Woods had been found earlier.

Valleck was a go-go dancer and was married at the time to Frank Michael Valleck III, a sailor from New Orleans, who became a person of interest; law enforcement were unable to locate him for questioning. Her murder was investigated as part of a broader inquiry into a series of Tampa Bay area killings in the 1970s sometimes called the Gulf Killer or Red Light Murders, a group of at least 16 victims (14 women and two men).

Serial killer Gerald Stano later confessed to Valleck’s murder, but authorities found insufficient evidence to conclusively link him to the killing. Other potential suspects have been identified over the decades but no charges were filed. Does anyone have information that could help solve Diana Lynn Valleck’s murder?
