Authorities say a southwest Ohio highway pileup involving at least 86 vehicles has left a 12-year-old girl dead.

The crash on I-275 was one of at least four pileups that snared dozens of vehicles in the state on Monday.

Parts of the state saw scattered snow showers, with isolated pockets of heavier snowfall.

The girl died in the I-275 pileup near the Cincinnati suburb of Colerain Township. At least 20 injured people were taken to hospitals.

The State Highway Patrol says an estimated 50 vehicles were in a pileup on I-75, between Middletown and Monroe. Minor injuries were reported there.

And the patrol says four semi-trailers and about 20 cars were involved in an afternoon pileup on I-71 near Mansfield.
