TUCSON - Authorities say a father and his four children were seriously injured after their vehicle rolled several times on a busy Tucson interstate.
Northwest Fire District Capt. Adam Goldberg says the family's SUV was traveling eastbound on I-10 Saturday afternoon between Ruthrauff and Prince Road exits when the accident occurred.
Goldberg says a 15-year-old girl, who was not wearing a seatbelt and was ejected from the car, suffered life-threatening injuries.
The girl's 22-year-old brother, who was driving, sustained critical injuries. An 18-year-old man and a 13-year-old girl suffered minor injuries. The 50-year-old father remains in serious condition.
Goldberg says the 18-year-old was also not wearing a seatbelt.
Arizona Department of Public Safety officers say the cause was tire failure and a separated tread.
The family was traveling from California to Mexico.
