Four people are dead following a wrong-way crash that occurred just after midnight on Sunday, according to the Arizona Department of Public Safety.
According to DPS, a wrong-way vehicle was reported driving southbound in the northbound lane on I-19 near milepost 46 around 12:45 a.m.
The wrong-way driver, a 52-year-old woman, collided head-on with a Nissan Sentra occupied by a mother and her three sons.
DPS says the mother, as well as two of her children, were killed in the crash. The third (and youngest) son was air-lifted to Banner UMC with life-threatening injuries.
The wrong-way driver also died in the crash. DPS says impairment will be determined by the medical examiner.
