Police in Indiana say a Michigan City man accidentally shot and killed a child in his care while playing a dangerous "gun game" with the boy.

Zachariah L. Grisham, 24, was arrested an charged with neglect and reckless homicide following the death of his girlfriend's son, 3-year-old Lance Wilson, this past Sunday.

According to Det. Sgt. Andy Hynek of the La Porte County Sheriff's Department the "gun game" Grisham would often play with Lance consisted of the boy pointing a finger gun at Grisham, followed by Grisham pointing his real gun at Lance and pulling the trigger.

Grisham told authorities he forget he had loaded the gun earlier that day.

"As an adult, you should know better than to play a game with a 3-year-old with a gun," neighbor Kim Vansickle told ABC Chicago. "You never know what could happen. And in this case, it went off and a little boy had to die."
