Police say she shot 21-year-old Matthew Dillingham on Tuesday after he shot at her while trying to run away from a traffic stop.
The Fairbanks Daily News-Miner reported Dillingham was a passenger in the stolen car. The driver ran away and has not been found.
Fairbanks Police Chief Laren Zager said Wells had not been involved in a police shooting before.
Police requested a special investigator from the Alaska State Crime Lab. The findings will be sent to the Fairbanks District Attorney's Office for review.
The shootout was captured on the video camera of Wells' patrol car, and Zager said her shooting appears to be justified.
"I think that judging by all the evidence we have, she just did a phenomenal job," he said.
The last fatal shooting involving a Fairbanks police officer occurred in August 2007 when a patrol officer shot a man who pulled out an unloaded handgun following a traffic stop. A state investigation found the officer's actions justified, and he remains with the department.
