On Monday, an Afghan-Canadian family was found guilty of the honor killing murders of three of four women, including three of the family's daughters and the husband's first wife. The four women were found dead inside a car in a canal, but prosecutors concluded that they were first murdered and then pushed into the water to cover up the crime.

The Quebec court determined that Mohammad Shafia, his wife Tooba Yahya and son Hamed killed the girls because they broke from the family's conservative values. One of the daughters was dating a Christian, one had a Pakistani boyfriend that her father didn't approve of, and the third daughter was caught wearing immodest clothes. The fourth victim, Shafia's first wife, never bore him children and was allegedly despised by Yahya, his second wife, who bore him seven.

In essence, the women were killed because they dishonored their family.

These types of murders happen all over the world, every year. In rural Brazil, London, Pakistan and North Africa, people -- especially young girls -- are put to death for the sake of eliminating a perceived stain from a family's legacy. It's an ancient practice but one that is still shockingly common today.
