About a year ago, a mentally disturbed Oregon man took some meth and decided to kill himself. He picked up a nailgun, pointed it at his head, and fired. Then fired som more. Stopped to reload. Kept firing until twelve 1-1/2" and 2" finishing nails were in his skull.
The next day, he went to a small hospital complaining of a headache.
Fortunately, doctors were able to remove all the nails, and the man has gotten treatment for his addiction and underlying mental illness.
