    'Who killed Theresa?:' 40 years later, brother seeks answers in Quebec cold case

    'Who killed Theresa?:' 40 years later, brother seeks answers in Quebec cold case

    "Quebec provincial police announced earlier this year it was beefing up its cold-case team to nearly 30 from five, in order to apply modern investigative techniques to some 750 unsolved cases going back 50 years.

    A photo of Theresa, grinning broadly and dressed in a green tank top, appears on the police's website next to a few details about her case, which is listed as "unresolved."

    "Although the case was treated as a disappearance at the time, over time all avenues of inquiry have been studied and still are today," said the blurb on the police website."

    The Sûreté du Québec will be launching a command post to assist in the search for two Indigenous women, who have been missing since September 6, 2008.

    Maisy Odjick, 16, and Shannon Alexander, 17, were last seen in Maniwaki, Quebec."

    Case Study: 30-Year-Old Cold Case Fingerprints Come to Light
    "Latent fingerprints are left with trace sweats and oils from unique patterns, providing the first great forensic human identifier about a century ago.

    One of the few problems, however: the fingermarks can dehydrate over long periods of time. Cold cases may thus be a challenge.

    But a team at the Sûreté du Québec police force in Canada has put together a methodology involving fuming, dyes and lasers which produced a clear fingerprint on a challenging plastic bag surface from a double-homicide scene from the 1980s, as they report in the journal Forensic Science International.

    “The current case presents a uniqueness due to the age of the revealed fingermark, and the paired success of cyanoacrylate fuming,” writes the Canadian team. “It would thus be of great interest of future cold case analysis using this technique to identify the factors having made this revelation possible.”

    The plastic bag was found at the crime scene, and had been preserved in a paper evidence bag for decades.

    Since the plastic bag is non-porous, it also further fostered the dehydration process in the roughly 30 years it was left untreated in storage. Its lack of texture also “eased the deposition process.”

    The Sûreté forensic experts decided to try fuming with superglue: namely E-Z Bond Instant Glue (Thin), with cyanoacrylate."


    "Once dry, an Arrowhead 532 nm laser was used to examine the patterns. Through orange-stained goggles, pictures are taken with a Nikon D7000 camera mounted with an orange-curved barrier filter.

    "A good fingerprint was thus produced for the first time from the two homicides."
    No suspect has yet matched the fingerprint from the double-murder scene, the team reports. However, the cold-case technique could crack open it and other cases in the near future, they report.


    “It also reiterates the importance opening cold cases in order to treat and reassess their exhibits,” they write. “Despite the age of a fingermark, cyanoacrylate combined with rhodamine 6G and visualized with a laser can provide new evidence … This opens the possibility of making an identification and ultimately change the course of the investigation.”
