A 37-year-old cold case in Miramar, Florida, was recently solved after investigators found DNA evidence linking a suspect to the brutal murder of William "Billy" Halpern in 1986.

Following a public appeal for information, Harry Collier was identified as one of the perpetrators, although he is now deceased.

Collier's DNA linked him to another double murder in Tamarac around the same time as Halpern's death.

The investigation also raised suspicions about the gym owner, Gil Fernandez, but DNA evidence was inconclusive.

The case remains open as authorities continue to seek more information and possible arrests.
