5 solved cold cases from the 1980s. Many cases of terrible crimes go unsolved for many years, but thanks to the improvements

of technology, some of these cases are reopened and solved.

Here are five solved cases from the 1980s.

Number five, Reset Treksler, 1984.

It's been 36 years since recent Trexler's horrific murder.

After a strenuous investigation, the case went cold for three and a half decades,

but only recently, with the use of DNA and genetic genealogy,

investigators were able to shed light on who killed the young girl.

It was June 15, 1984, when the 15-year-old was found naked in her bedroom at her

grandparents' house in North Carolina.

Upon closer examination, investigators found multiple stab wounds

and that her spinal cord had been completely severed.

The steel blade was actually still lodged in Trexler's right shoulder during the autopsy.

Even more damning, seaman, supposedly from the killer, was recovered from her body.

The initial investigations went nowhere, and so for over three decades the case went cold.

Rumors were rampant around the small town of Salisbury about who could have committed such a gruesome act.

Some even said that Trexler's sister, who was 13 years old at the time, was the culprit.

She appeared on the Dr. Phil's show in 2018 to take a polygraph

test to prove her innocence and that appearance sparked new interest in the case.

According to Sergeant Travis Schullenberger from the Salisbury police,

detectives went back and reviewed the evidence, conducted interviews, and collected DNA samples

to try to solve this seemingly impossible case.
