This monster has to be executed! There's no rule in Sharia that a Father / Husband canot be executed.
Rule is simple, as long as its proven that HE IS THE KILLER, and unless the affected party(the girls mother) accepts DIYA and excuse, he has to be EXECUTED!

@ Marco Nandoz - Keep your stupid racial comments away from this. These kinds of killing happens in all parts of the world, and i doubt that killer would receive this harsh punishment in any other law! so just shush!
