PHOENIX — An Arizona trooper fatally shot an armed driver who nearly ran over another trooper who was trying to stop him and later crashed into several police vehicles at the end of a high-speed chase on Phoenix-area freeways, state officials said Monday.

The trooper shot the man Sunday night when he was seen with a gun and perceived to be a threat, Department of Public Safety spokesman Raul Garcia said.

No additional information was immediately available, including the dead man’s name and information on the gun he allegedly carried.

Part of a north Phoenix freeway where the crash and shooting occurred was closed for over nine hours, including the morning commute, as authorities investigated.

Garcia said the chase began about 10:30 p.m. when a trooper tried to pull over a vehicle for a traffic violation on the Loop 101 freeway. The suspect reached speeds over 100 mph during the pursuit that covered a portion of U.S. 60 before returning to the 101, Garcia said.

At one point, the suspect veered toward a trooper on the shoulder of the road who was trying to deploy tire puncturing devices, according to Garcia.

“Our trooper injured his ankle while attempting to avoid being hit,” Garcia said in a statement.

Just after 11 p.m., the suspect’s vehicle struck several DPS patrol vehicles on the 101, Garcia added.

Troopers at the scene then saw “the suspect had a firearm and one of our troopers in fear for his life and those around him fired at the male suspect,” Garcia said.

Troopers rendered aid but the man was pronounced dead within an hour.
