MEMPHIS, Tenn. — A trial date has been set for Treveno Campbell.

Campbell is charged with shooting to death Memphis police officer Martoiya Lang in December 2012.

Shelby County Criminal Court Judge James Beasley set a June 20 trial date.

Campbell has pleaded not guilty to first-degree murder.

Authorities say Lang was killed and another officer was injured when police entered a home where drug trafficking was suspected, and a suspect inside the house opened fire with a 9mm pistol with a high-capacity magazine.

Campbell was shot during the raid.

Lang was a mother of four children.

She is one of four Memphis police offices to be fatally shot since July 2011.
