Mobile police said they will not file charges in the Monday shooting death of an 11-month-old child.

Police said the 11-month-old, whose age was initially reported as 1 year old, was shot in the back by his 2-year-old brother. The 11-month-old was taken to the Providence Hospital and pronounced dead a short time later.

Police presented the facts of the case to the Mobile County District Attorney's Office, which determined there were no elements of probable cause to prompt criminal charges, said Mobile police spokeswoman Charlette Solis.

Police responded to the 8000 block of Domain Street at 2:28 p.m. in reference to an 11-month-old shot.

The childrens' parents told police their 2-year-old found their gun and shot the 11-month-old, police said. At least four children live at the residence where the 11-month-old was fatally shot.

Mobile Police Chief Lawrence Battiste said Monday he thought the shooting involved a 9mm handgun that had been kept in the parents' bedroom.

The mother was about to leave the house, and she went out back to what Battiste described as a mother-in-law suite to speak to her mother-in-law.

"She had gone out back to let her know that she was getting ready to leave the residence when we believe the 2-year-old came out and told his grandmother that his ears were ringing," Battiste said Monday.

"Regardless of how this business plays out, as a parent to know that you possibly left a weapon where your child could be injured, you've got to live with that pain for a long time."
