Highway authorities are investigating after a man was killed in a collision in Tolleson.

The Arizona Department of Public Safety said Matthew Dillion Kinnard, 27, was pronounced dead at the hospital after being involved in a two-vehicle collision around 12:30 a.m. Wednesday on Interstate 10 near 91st Avenue.

DPS said Mr. Kinnard was driving a gray Toyota sedan on southbound on Loop 101 when, for an unknown reason, he drove off left though some landscape onto eastbound I-10, cut across all lanes, and struck a cement barrier wall.

Mr. Kinnard became stuck in his disabled vehicle in the No. 2 lane on I-10. DPS said his vehicle was then struck by a Toyota Prius hatchback that was traveling eastbound. DPS said the female driver of the hatchback swerved left to avoid hitting the sedan but still struck the front of it, causing her to go into the cement median.

Mr. Kinnard was taken to Banner Estrella Medical Center where he later died.

DPS said Mr. Kinnard was not wearing his seat belt and no airbags were deployed. The driver of the other vehicle was also taken to a hospital with non-life-threatening injuries.

DPS named her in an email but is not being named here since she has not been cited or charged.

The Maricopa County Office of the Medical Examiner lists seizure disorder as a contributing cause of death for Mr. Kinnard.
