A three-year-old Michigan boy is dead after accidentally shooting himself in the head with a .40-caliber handgun at a home on Sunday afternoon in Lenawee County's Franklin Township.

Michigan State Police say Jonathan Kaufman found the loaded pistol in a closet while his father and older brother were outside and fatally wounded himself with a single shot.

State troopers and emergency medical personnel were dispatched to the scene, but they could not save the boy and he was pronounced dead.

The death is still under investigation.

A report will be sent to the county prosecutor's office for review, which typically happens in such cases.

In an eerily similar incident in 2013, three-year-old Damon Holbrook died after finding a loaded gun in a closet at his family's home in Dundee, Michigan, and shooting himself in the head.

A friend of the boy's father left the gun on the floor of a bedroom closet in an unlocked case after returning home from work.

After the death of his son, Brian Holbrook backed the right to bear arms in a Facebook post.

He said 'I have nothing wrong with guns, I will still support the Second Amendment [sic].

'All I ask is that everyone please, please safety first... lock it up and put it out of reach of anyone that has no business being around a gun especially kids.

'Gun safety people! My boy would still be here if it was put away like it should have been.
