1978 Disappearance & Discovery
Theresa Allore was a 19-year-old Canadian college student who disappeared on Friday, November 3, 1978 from Champlain College Lennoxville in the Eastern Townships of Quebec. Five months later, on April 13, 1979, her body was discovered in a small body of water approximately one kilometer from her dormitory residence in Compton, Quebec.  Upon her disappearance police initially suggested she was a runaway. When her body was discovered police then suggested that she was the possible victim of a drug overdose, perhaps with the assistance of fellow college students. 
In the summer of 2002, the family of Theresa Allore enlisted the support of an investigative reporter and friend, Patricia Pearson, who produced a series of articles for Canada's National Post newspaper that presented compelling evidence that Theresa Allore was a victim of murder, and that her death was possibly linked to two other unsolved local cases; the death of 10-year-old Manon Dube in March 1978, and the murder of Louise Camirand in 1977. The theory was supported by geographic profiler and then FBI consultant, Kim Rossmo, who suggested a serial sexual predator may have been operating in the Quebec region in the late 1970s and advised police to investigate the three deaths as a series. Rossmo later gained notoriety when, in 1998, he suggested that Vancouver police create a serial killer task force to investigate the multiple cases of missing women from Vancouver's downtown Eastside.  Robert Pickton was eventually arrested and found guilty of six murders, though he was accused of, and implicated in, an additional 26 murders of Vancouver missing women. 
The deaths of Theresa Allore, Manon Dube, and Louise Camirand remain unsolved cold-cases.
Since 2002, John Allore - who maintains the website, Who Killed Theresa? - has continued the investigation. Allore has geographically identified 15 unsolved murders from 1975 to 1981 which may be associated. The related cases are: Sharron Prior , Lise Choquette , Louise Camirand , Jocelyne Houle , Chantal Tremblay , Johanne Dorion , Hélène Monast , Katherine Hawkes , Denise Bazinet , Manon Dube , Lison Blais, Theresa Allore, Nicole Gaudreaux, Tammy Leakey, and Johanne Lemieux.
The Surete du Quebec's Cold Case Squad
For years John Allore lobbied for the creation of a Surete du Quebec cold case unit. In 2004 the squad was created, with a mandate to solve over 600 cases under its jurisdiction. The first case added was Helene Monast.  In 2018 the Surete du Quebec added 25 officers to the unit, significantly increasing its capacity.  By the spring of 2018 all the major cases referenced by John Allore that were under the Surete du Quebec's jurisdiction - Louise Camirand, Chantal Tremblay, Helene Monast, Denise Bazinet, Manon Dube and Theresa Allore - had been added to the Surete du Quebec's cold case website. 
Beginning in 2018 John Allore started to focus on Quebec cases from the 1980s and 1990s, cases that further suggest systemic failures in Quebec criminal justice. The related cases are: Lyette Gibb , Sophie Landry , Chantal Rochon  , Valerie Dalpe , Marie Eve Lariviere , Melanie Cabay , Marie Chantale Desjardins , Joleil Campeau , Debbie Buck , Johanne Beardoin, Danielle Laplante, Jolène Riendeau  , Julie Surprenant and Cedrika Provencher.
