The son of former Canadian Prime Minister Jean Chretien and the sister of convicted serial killer Karla Homolka testified on Friday at the murder trial of a Canadian man who has admitted to killing and dismembering a Chinese student in 2012.

Canadian Luka Magnotta used the names and addresses of Chretien's son and Homolka's sister as return addresses of grisly parcels sent to two elementary schools in Vancouver, jurors heard.

The packages, along with two sent to two political parties in Ottawa, contained the hands and feet of murder victim Jun Lin.
