The officer involved in a fatal shooting in Marlow on Saturday was Deputy Steven Williams, Anderson County Sheriff Paul White said Thursday morning.

Authorities had earlier declined to name the officer.

White said Williams has been a reserve deputy with the Anderson County Sheriff’s Department since July 2008 and a senior patrol officer as of June 2012.

“He is one of only six reserve deputies out of 38 that have received advanced training and have the necessary qualifications to be used on patrol,” White said.

On Sunday, the Tennessee Bureau of Investigation identified the man who died as Randall Kyle Wilcox, 30, of Clinton.

Authorities said Wilcox was shot after he tried to take Williams’ weapon. Williams had chased Wilcox on foot after a traffic stop at about 10:22 a.m. Saturday on Pine Ridge Road in Marlow.

“The driver pulled into a driveway, jumped from the car, and fled on foot,” White said. “Deputy Williams gave chase and a short distance later was confronted by the suspect, where a struggle ensued with the suspect trying to take his duty weapon. The suspect was shot and killed.”

After the shooting, Williams was taken by ambulance to Methodist Medical Center in Oak Ridge, where he was treated and released, White said, although he didn’t identify the type of injuries.

White said Williams has received his initial “critical incident stress debriefing,” and there will be more debriefings for him and other law enforcement officers.

“Since a shooting is one of the most traumatic events an officer will ever experience, we want to ensure Deputy Williams is ready to return to his duties,” White said.

He said the department’s incident report is not complete. “We will notify when it is available for release,” White said.

The Tennessee Bureau of Investigation has been asked to investigate, which is standard when an officer is involved in a shooting.

Authorities haven’t said why Williams stopped Wilcox, but TBI Public Information Officer Kristin Helm has said it was for a non-moving violation. Wilcox had a lengthy record that includes 20 arrests dating back to 2000, including for carjacking and assault charges, according to county records and the Sheriff’s Department.

Anderson County Sheriff’s Department Chief Deputy Mark Lucas said Wilcox was wanted on three outstanding arrest warrants, two for contempt of court and one for failure to appear.
