A Tennessee sheriff’s deputy was fatally shot during a traffic stop Wednesday, and police were searching for a suspect believed to be “armed and dangerous,” authorities said.

Authorities identified the suspect as Steven Wiggins, a white male with balding brown hair.

The Tennessee Bureau of Investigation tweeted that it has placed Wiggins on its Top 10 Most Wanted list and is offering a reward of up to $2,500 for information leading to his arrest.

The agency also sent an alert about the suspect to cellphones in the area.
