Two children died and two adults were seriously hurt in a rollover accident on the New York State Thruway.

The accident happened just before 6am Monday on the I-90W between exits 42 (Geneva) and 43 (Manchester).

Two children, Amir Middleton, 9, and his brother Shamel Middleton, 11, both from Buffalo, were pronounced dead at the scene. The family was returning home from a trip to Brooklyn.

The driver, Sean Ferguson, 31,  was taken to Strong Memorial Hospital. He is currently in critical condition. The mother of the two boys, Shenaya Washington,34, was a passenger in the vehicle.  She was hurt, but expected to be ok.

Troopers say they arrived to find an SUV on its side in the right lane. Investigators believe the vehicle struck a guardrail then rolled over several times before coming to a stop. Both boys were ejected from the vehicle.

Police say another driver may have unknowingly run over one of the boys following the accident.  That driver is not expected to be charged.

The accident is still under investigation.
