I wonder what the tally is already for this year? When is enough going to be enough?

(CNN) -- A 3-year-old boy in a small Michigan town was killed over the weekend when he accidentally shot himself in the head with a gun he found on the closet floor of his home.

The shooting death will undoubtedly renew the debate about gun safety, particularly after the boy's father took to Facebook calling for it.

The incident took place Sunday at a home in Dundee, near the Ohio border.

Police said Damon Holbrook discovered the gun, which belonged to a family friend who was living in the house.

Authorities told CNN affiliate WXYZ that the family friend, Joshua Greenhill, had a concealed pistol license and he put the .40 caliber handgun in the closet. It was loaded, with a bullet in the chamber -- but was not locked.
