Montreal-area police say they are working with law enforcement agencies in Canada and the United States to determine whether a man newly linked to a 1975 cold case may have been responsible for other unsolved murders.

Investigators in Longueuil, Que., south of Montreal, said Tuesday that DNA evidence establishes with certainty that Franklin Maywood Romine raped and murdered 16-year-old Sharron Prior nearly 50 years ago.

Now police say theyB次元官网网址檙e trying to find out whether Romine B次元官网网址� a career criminal who died in 1982 at the age of 36 B次元官网网址� may have had other victims.

B次元官网网址淲e are already working on it, but not only in Canada, weB次元官网网址檙e also working with the FBI to see if thereB次元官网网址檚 any link with other cold cases in the U.S.,B次元官网网址� Longueuil police Sgt.-Det. Eric Racicot, who investigated the Prior cold case, told reporters.

PriorB次元官网网址檚 younger sister, Doreen, said the confirmation that police identified her sisterB次元官网网址檚 killer brought a B次元官网网址渓ong and difficult journeyB次元官网网址� to an end.

That journey began over the Easter Weekend in 1975, as she, her twin sister and their brother looked through a window in the family home in MontrealB次元官网网址檚 Pointe-St-Charles neighbourhood hoping to see Sharron Prior return home.

B次元官网网址淭he solving of SharronB次元官网网址檚 case will never bring Sharron back,B次元官网网址� Doreen Prior said Tuesday. B次元官网网址淏ut knowing that her killer is no longer on this earth and cannot kill anymore brings us to somewhat of a closure.B次元官网网址�

Maureen Prior, DoreenB次元官网网址檚 twin sister, thanked Racicot and Lt.-Det. Sophie Touga for never giving up on the case.

B次元官网网址淲ithout your skill, dedication and countless hours of investigation, we would not be hear today,B次元官网网址� she said. B次元官网网址淵ou pushed new technology to its boundaries and brought us answers we have been waiting 48 years to hear.B次元官网网址�

The rape and killing of Prior had gone unsolved since she disappeared on March 29, 1975, after setting out to meet friends at a pizza parlour near her home. Her body was found three days later in a wooded area in Longueuil.

Police investigated 122 suspects, but Romine was not among them.

In 2015 scientists sequenced a complete DNA profile from a shirt used to restrain Prior B次元官网网址� but that specimen was only a partial match with a sample found on her jeans.

But by 2022, technology had improved, allowing scientists to amplify small samples of DNA for study. That year Racicot sent the shirt and the jeans to QuebecB次元官网网址檚 legal science laboratory for retesting, and for the first time a complete and matching sample was found on both clothing items.

It was at that point that the legal science laboratory suggested a new technique: analyzing the Y chromosome in the DNA sample.

Passed down unchanged from father to son, the Y chromosome can be compared with DNA samples in databases containing thousands of profiles collected from people through commercial testing kits from companies such as 23andMe or AncestryDNA.

The Y chromosome found on the jeans and the shirt was compared with profiles in an American database and it matched with a family name: Romine.

As QuebecB次元官网网址檚 legal science lab reconstructed a Romine family tree, RacicotB次元官网网址檚 police work led him to determine that a Franklin Maywood Romine had been living in Montreal at the time of the killing and that other evidence pointed to him. RomineB次元官网网址檚 appearance corresponded with a witnessB次元官网网址檚 physical description of the suspect; RomineB次元官网网址檚 car was compatible with the tire tracks at the site where police found PriorB次元官网网址檚 body 48 years ago.

Meanwhile, Quebec scientists traced the Romine DNA to four brothers from West Virginia. And on May 2, Racicot and several colleagues were present as local authorities in West Virginia exhumed RomineB次元官网网址檚 remains for DNA testing to confirm his link to the crime.

B次元官网网址淭he resolution of this cold case is based on new investigative techniques but also on advances in forensic biology,B次元官网网址� Racicot told reporters. B次元官网网址淭hese are new tools that we didnB次元官网网址檛 have a few years ago and itB次元官网网址檚 a powerful one.B次元官网网址�

The DNA is B次元官网网址渓ike a guiding lead,B次元官网网址� he said. B次元官网网址淚t still needs to be confirmed by classic investigation techniques.B次元官网网址�

Romine, whose criminal record began when he was a child, was on the run from the law in West Virginia at the time of PriorB次元官网网址檚 death. On parole since 1973, he was facing new charges of breaking and entering and rape.

He fled to Montreal, where he lived until around seven months after PriorB次元官网网址檚 murder, when he was arrested by Montreal police and extradited to the U.S. But by 1982, he was back in the city. He died there of unknown causes, but his body was buried in his hometown of Fraziers Bottom, West Virginia
