Maricopa County Sheriff's Office is investigating after a serious crash on Grand Avenue late Sunday morning that left one driver dead.
An older man driving a van north on 107th Avenue is believed to have had a medical issue as he entered the intersection of Grand Avenue, hitting a red SUV that was stopped at the light. MCSO said the 76-year-old driver died.
The van then hit another vehicle occupied by a mother and two children that rolled upon impact.
The mother and children were taken to the hospital with non-life threatening injuries.
MCSO believes the man may have had a medical episode because "his car has minimal damage and the airbags deployed, but it's not consistent with the damage of a fatal accident," Deputy Joaquin Enriquez said.
The roads were closed down for a few hours as investigators worked in the area, but did reopen around 2:40 p.m.
The exact cause of the crash has not yet been confirmed by traffic detectives.
US 60 (Grand) is now closed in both directions between 107th and 111th avenues. No ETA for reopening.
