In numerous cases of these so-called "honor killings", the female members of the family are actually accomplices helping the killers. I recall seeing one case on Court TV in Missouri where both father and mother were tried, convicted and sentenced to death for something similar (although no executions have been, nor will be carried out, the father have died of cancer prior to his execution, and the mother's sentence being commuted...)

True, but I didn’t see anything in the story implicating the mother, just the savages who actually did it.
