Linda Andersen (April 15, 1959 – January 18, 2003) was the victim of premeditated murder by her two teenage daughters, Sandra and Elizabeth Andersen, on January 18, 2003 in Mississauga, Ontario. The names Linda, Sandra and Elizabeth Andersen are aliases created by Bob Mitchell in an effort to protect their identities. The girls' real names were put under a publication ban by the crown because they were under 18 at the time of the murder. ... Wikipedia.org
