Authorities arrested a man in a decades-old Massachusetts double murder mystery.

Timothy Joley, 71, was taken into custody at his home in Clearwater, Florida, Oct. 30, nearly 46 years after he allegedly shot and killed 18-year-old Theresa Marcoux and 20-year-old Mark Harnish, the Hamden District Attorney's Office announced Wednesday.

The victims were found shot to death near Harnish's pickup truck parked in a Springfield, Massachusetts rest area Nov. 19, 1978.

A patrol officer noticed the vehicle was damaged and there was evidence of blood in and around the truck. Marcoux and Harnish's bodies were discovered over a nearby guardrail. Both victims had been shot several times, the medical examiner determined, according to the DA.

The pair were last seen leaving a friends party together hours before they were fatally shot. Investigators determined Marcoux and Harnish were killed in the truck and their bodies were dragged over the guardrail after.

At the time, ballistics and bloody fingerprint evidence found in the truck yielded no leads, and the case went cold.

"However, in just the last month, information was received from an individual who provided investigators with the name of Timothy Scott Joley and information as to Joley's purported involvement with the deaths of Theresa Marcoux and Mark Harnish," the DA's office said in a Facebook post.

Further investigation and advancements in fingerprint technology allegedly proved the bloodied print found in the truck matched the fingerprint on Joley's application for a taxi license, according to WCVB-TV. It was also learned Joley bought a gun a month before the alleged murders.

A motive remains under investigation.

Joley is expected to be extradited back to Massachusetts in the coming weeks.
