A rollover crash in Porter County ejected the driver and a four year-old child on I-94.
Indiana State Police say the vehicle, driven by a 23 year-old Gary woman, was westbound near mile marker 18 when a tire blew out and she lost control.
The driver and a four year-old boy were ejected while the vehicle rollen numerous times. A two year-old girl in the vehicle in a child seat and a 23 year-old passenger remained in the vehicle and were not injured.
The adults are the parents of the children.
The four year-old sustained a leg injury and the mother was airlifted with life-threatening injuries.
