Investigators from the Terrebonne, Sainte-Anne-des-Plaines, Bois-des-Filion Intermunicipal Police Department are looking for witnesses who may have been in contact with or may have hired Claude Vallières for homework help.
According to police, Vallières, who used to go by the name Claude Paquette, placed an ad on Kijiji offering tutoring services and homework help for grade-school children.
The 36-year-old, a former teacher, was previously convicted in 2016 of sex offenses related to child pornography.
