TUCSON, Ariz. (KVOA) – A tragic multi-vehicle collision on January 2 has resulted in the death of a 4-year-old boy and left several others with serious injuries.

According to a press release, the crash occurred at approximately 7:45 p.m. on the 5300 block of East Golf Links Road. A Toyota Corolla, driven by a 27-year-old woman, crossed into oncoming traffic, colliding with a Toyota Camry and a Volkswagen Jetta.

According to the Tucson Police Department, the Corolla driver and her four children were taken to Banner University Medical Center with life-threatening injuries. Sadly, the 4-year-old boy succumbed to his injuries at the hospital.

The Camry’s driver and passenger sustained serious but non-life-threatening injuries, while the Jetta’s driver suffered minor injuries.
