MILWAUKEE (AP) — A 2-year-old boy fatally shot his mother from the back seat of the car as she drove along a Milwaukee highway, sheriff's officials said Wednesday, less than two months after a Florida mother was shot and wounded in similar circumstances. The child, who was sitting in the back seat, picked up a gun that slid out from under the driver's seat and fired it through the front seat, striking Price, the department said in a statement, citing witness accounts. A .40-caliber gun was recovered from the floor of the back seat behind the driver, along with a security officer's gun belt belonging to the victim's boyfriend, sheriff's officials said. After the shooting, deputies performed CPR until emergency medical personnel arrived.
