The boy used the gun of Sonday Bishop, who lives with the child and his mother in an apartment, according to police. Bishop did not keep his .22 caliber handgun in a lockbox, and the boy knew where the gun was kept, police said.
"He pretty much sees where I'm putting it," Bishop told the Union Leader.
The boy is recovering in the hospital and doing well. Manchester police could not yet say whether Bishop would face charges, according to the Union Leader.
