Patrice Price, 26, was driving down a Milwaukee highway on Tuesday when her son fired a .40-calbier pistol through the back seat of the blue Dodge Sedan, the Milwaukee County Sheriff's Office said in a statement. Officials found the gun on the floor of the back seat, behind the driver's seat, police said.
Officials said the gun and the car belonged to Price's boyfriend, who works as a security guard. The boyfriend's gun belt and tactical vest were also in the vehicle at the time, police said in the statement.
Police said the toddler was not in a car seat and "retrieved a firearm that slid out from under the driver's seat and shot through the seat, striking the driver."
Other motorists stopped and pushed the car out of traffic's way before deputies arrived and performed CPR on the mother. She was pronounced dead at the scene.

Price's mother and 1-year-old son were also in the car at the time, authorities said.
Price's mother said she heard a loud pop from the back seat of the car, after which Price turned to her and said, "Momma, don't let me die," WISN reports.

One day after her death, family and friends gathered on a Milwaukee street to remember the 26-year-old mother, Fox reports.
The Milwaukee tragedy bears similarities to a March incident in which a Florida woman was shot by her toddler son while driving.
Police say the Florida woman, Jamie Gilt, was driving down a highway when the 4-year-old somehow got his hands on his mother's handgun and the weapon went off. Gilt survived the shooting.
