Investigation and Suspects
In October 1977, a special unit of fifteen law enforcement officers from three counties was formed to capture the perpetrator(s). Interviews with local sex workers, strippers, and barmaids revealed that many victims were single and worked on or frequented the Dale Mabry Strip—a mile-long area known for its bars, adult bookstores, strip shows, and X-rated movie houses. Five victims were shot in the head with a .22 caliber gun, three were found nude, and three others were partially nude. Two had been strangled, and all sex worker victims had their purses stolen. Authorities believed the victims were killed at undetermined locations and then dumped where they were discovered. Several suspects emerged during the investigation:- Gene Arthur Wirtjes
- Details: On January 12, 1979, Wirtjes was sentenced to 25 years in prison for the murder of Jo Ann Parnell. He had killed Parnell to prevent her from testifying in an aggravated battery case involving a stabbing that occurred at a local bar on July 5, 1977.
- Gerald Stano
- Details: Convicted serial killer Stano confessed to the murders of Diana Valleck, Enid Branch, Joan Foster, and Emily Grieve, among 37 others. However, he later recanted, claiming he was forced to make false confessions by the lead investigator.
- Jerry Frank Townsend
- Details: In 1979, Townsend, a 28-year-old itinerant laborer, was arrested for raping a woman in Downtown Miami. He confessed to several murders and was once considered a suspect in the Pasco County killings. However, he was released in June 2001 when it was determined that he was not involved in the murders, had an IQ of 56 and the mental capacity of a 7-year-old, and had been pressured to falsely confess.
