Possible road rage investigated in I-10 fatal crash

Authorities are investigating whether road rage was a factor in a collision last week that left one man dead and prompted the closure of Interstate 10 for several hours during the morning commute.

The Department of Public Safety’s Vehicular Crimes Unit closed Interstate 10 at 40th Street, near Arizona 143, on Wednesday morning to investigate reported possible road rage, according to Bart Graves, a DPS spokesman.

“They’re continuing to investigate all angles,” Graves said Tuesday. “We don’t know definitively if this was road rage,” he added.

Details on what led officers to begin a road rage investigation have not been released.

Edward H. Twigt III, 46, of Chandler, was driving alone about 5:30 a.m. in the westbound HOV lane when a Honda Ridgeline crossed several lanes of traffic and sideswiped his white Toyota pickup truck, causing it to strike a concrete barrier, flip sideways and roll, Graves said.

Twigt was pronounced dead at the scene.

The Honda driver, who was also alone, remained at the collision and is cooperating with investigators, Graves said.

For a time, traffic had been allowed through the area of the wreck with three lanes open, but rush-hour traffic was still backed up nearly a mile.

After the interstate section was shut down, many Tempe streets were filled or blocked by traffic. Several residents reported having problems getting onto nearby main streets because of the increased traffic throughout Tempe.

Anyone with information regarding the collision is asked to call the Department of Public Safety at 602-223-2000.
