(AP) — A central Nebraska toddler remains in critical condition after being accidentally run over by his uncle.

Hastings Police Sgt. Jim Baldwin says 3-year-old Aldo Yoel Ramirez-Lopez was struck Saturday evening in a trailer park.

Baldwin says the boy’s uncle, 21-year-old Miguel Lopez, was parking a Ford Expedition and didn’t see the boy approaching from between several parked vehicles.

The boy’s injuries are life-threatening. He was flown to the University of Nebraska Medical Center in Omaha for treatment.

Police do not believe alcohol was a factor.
