UTICA, Wis. (AP) — Two young girls died after their ATV crashed into a car in east-central Wisconsin, authorities said Wednesday.

The Winnebago County Sheriff’s Office said in a series of news releases that the ATV collided with the car in the town of Utica about 12:41 pm Tuesday, WLUK-TV reported.

The ATV’s occupants, 11-year-old Mesa Fredenhagen and 7-year-old Kennedi Harris, both of Oshkosh, died. One of the girls was pronounced dead at the crash. The other was taken to a hospital and later died.

The news releases did not say which girl died on site or when the second girl died. A message The Associated Press left at the sheriff’s office seeking those details was not immediately returned.

The sheriff’s office said the 43-year-old woman who was driving the car had minor injuries, but she and her 13-year-old son, who was a passenger in the vehicle, tried to render first aid to the girls. She is cooperating with the investigation, the office said.
