US man accidentally kills self while demonstrating gun safety

An inebriated man in the US accidentally shot himself to death while teaching his girlfriend about gun safety.
The 36-year-old man, from Independence Township in Michigan, was showing his girlfriend how to use his three handguns and demonstrating how safe they were when they were unloaded.
So he placed a gun to his head and pulled the trigger. After doing this twice, he demonstrated the third handgun, but the gun fired a bullet. He was pronounced dead at the scene.
The girlfriend told officials the victim had been drinking most of the day, 'The Oakland Press' reported.
"(The situation) is pretty unique, as I have never heard of anyone testing out the safety of a gun by pointing at their head and pulling the trigger," Oakland County Undersheriff Michael McCabe said.

Three children, ages 7, 10 and 12, were present at the time of the shooting, earlier this week, but they did not witness it.
The children are not the biological kids of the victim.
