An Afghan father, his wife and their son have been jailed for life after being found guilty of killing three sisters and another woman in what a judge described as "shameful murders" resulting from a "twisted concept of honour".
The jury in Ontario found Mohammad Shafia, 58, his wife Tooba Yahya, 42; and their son Hamed, 21, each guilty of four counts of first-degree murder.
Prosecutors said the daughters were killed because they defied rules on dating and going online. The fourth victim was Shafia's first wife, who was living with the family in Montreal. The polygamous relationship could have resulted in their deportation.
