You never know who your neighbours are.
Media reports say convicted killer Karla Homolka is now living in Chateauguay Quebec.
That bombshell came out when her older sister was testifying in the Luka Magnotta murder trial.
A letter has gone home to parents at the Centennial Park Elementary school reassuring parents their children are safe.
Homolka goes by the name Leanne Bordelais.
Homolka struck a deal in 1993 and served 12 years in prison for her part in the Leslie Mahaffy / Kristen French murders with her then husband Paul Bernardo.
