TYLER, Texas (AP) — Investigators say a tire blowout caused an overloaded SUV to crash in East Texas, killing two boys and three girls on their way to a water park.

Department of Public Safety trooper Jean Dark says three other children and two adults were hurt in the single-vehicle rollover Monday near Van, about 70 miles east of Dallas. One adult and one child were uninjured.

Dark said Tuesday that the driver lost control of the GMC Envoy, which rolled several times before stopping on its top. She says the SUV did not have child safety seats and that nine of the children were ejected from the vehicle.

DPS identified the children who died as 13-year-old Rosvaelia Jaimes; 7-year-old Omar Jaimes; 6-year-old Saideth Acuna; 3-year-old Ulisa Acuna; and 2-year-old Judith Jaimes. All were from Marshall.
