Fatal Irvine car crash leaves Tustin woman dead, suspect arrested on suspicion of DUI

A 28-year-old La Quinta resident was arrested on suspicion of driving under the influence in connection with a two-car vehicle collision in Irvine that left an 83-year-old woman from Tustin dead, police said.

Just after 9 p.m. on Thursday, October 15, the Irvine Police Department and the Orange County Fire Authority responded to a traffic collision in the intersection of Harvard Avenue and Paseo Westpark in Irvine.

Upon arrival, officers found a 2009 Toyota Corolla and a 2023 Mercedes S680 in the intersection with “heavy collision damage,” said Ziggy Azarcon, a spokesperson with the Irvine Police Department.

Effat Setayeshgar Tinoosh, 83, the driver of the Toyota, was transported to a hospital where she died from her injuries, Azarcon said.

Twenty-eight-year-old Adam Gabriel Canchola of La Quinta, the driver of the Mercedes, was arrested on suspicion of driving under the influence.

“The suspect was booked, processed, and released. The additional charges may follow while the investigators are still looking into the evidence,” Azarcon said. The fatal collision is being investigated by Irvine PD’s Major Accident Investigation Team, who will be looking into inspections of the vehicles, roadway conditions, witness statements, or video footage that may be available to try to find the cause of the collision.
