Tucson police closed the intersection of Fort Lowell and Tucson Blvd. Friday morning due to a deadly crash.
The deceased driver of the Altima has been identified as 65-year-old Kathleen Forshay.
Officers and members from the Tucson Fire Department responded to the three vehicle collision at 7:20 a.m.
TPD says Forshay was immediately transported to Banner UMC with life-threatening injuries.
The adult drivers of the other vehicles were not injured.
Shortly after the woman arrived at the hospital, the woman succumbed to her injuries and was pronounced deceased.
Detectives from TPD's Traffic Investigations Unit responded to the scene to continue their investigation.
They interviewed multiple witnesses and collected evidence.
Detectives were able to determine the adult male driver of white 2008 Ford Edge Sport Utility Vehicle was eastbound on Fort Lowell in the median lane approaching North Tucson Blvd.
TPD says the driver was traveling above the posted speed limit and struck the side mirror of a white 2016 Subaru Forester that was eastbound on Fort Lowell Road, slowing for a red light at Tucson Blvd.
The driver of the Edge failed to stop for the red light at North Tucson Blvd. and struck the driver's side door of a gray 2015 Nissan Altima headed northbound on Tucson Blvd. on a green light.
Detectives are continuing their investigation and say impairment does not appear to be a factor in this collision.
No arrest or citation has been issued at this time.
