I think I know the answer

Terrible story today, about a kid killed at a house party in my old neighborhood in Calgary, Canada:

Blood-curdling screams filled the air in Queensland late Saturday night after a teen was murdered at a house party, struck in the face with a pickaxe during a fight. ...Lisa Poole, who lives two doors from where the murder took place, rushed outside when she heard the commotion, and someone asked her if she knew CPR. "I said 'why,' and she said, 'because I think he's dead'. I saw one boy laying there with a pickaxe stuck through the front of his head and some blood on the ground."

That's pretty awful, but at the end of the article it says:

Forsen said an autopsy is scheduled for today.

I think I can save them the expense and trouble: Cause of death? Pickaxe in head.
