KESQ News in California is reporting that a woman accidentally shot her 12-year old daughter in the arm by mistaking a tiny NAA mini-revolver with a gun-shaped cigarette lighter.

Police today were trying to figure out how a .22-caliber revolver wound up on the ground outside a Banning mobile home, where a woman mistook it for a cigarette lighter and accidentally fired it, wounding her 12- year-old daughter.

The girl's mother, 30-year-old Rachel Avila, and her daughter were talking with friends when Avila spotted what she thought was a gun-shaped cigarette lighter on the ground, picked it up and pulled the trigger to light it, Diaz said. The weapon discharged, firing a bullet that ricocheted off the ground and into her daughter's upper arm, he said.
