Tad Waddell,of Sheffield, Alabama, was cleaning his .45-caliber handgun when he unintentionally discharged the gun. The bullet went through the wall of his apartment into the apartment next door and struck James Gray in the chest.
Gray was taken to the Huntsville Hospital where he is listed in critical condition.
"It's just crazy, I don't know," said a neighbor. "Words can't describe how I feel about this, it's just unbelievable to shoot through a wall and hit somebody and put them in critical condition."
Police will present the findings of their investigation to the District Attorney to see if any charges should be filed against Waddell.
"It was stupid, stupid what happened," said the local police chief. "But one thing we have to say is, yeah it was an accident, this person does not appear that he intentionally done this, but you have to remember that there is a guy fighting for his life right now."
