MEMPHIS, Tenn. — The man found guilty of murdering a Memphis police officer was sentenced by a Shelby County judge on Tuesday.

Treveno Campbell will have to serve 31 years of the 40 year sentence at 100 percent in order to be eligible for parole in 2042.

The shooting happened in 2012 when police were executing a search warrant for drugs at Campbell’s home. Campbell fired shots — he said he didn’t know it was police — killing Lang and injuring another officer, William Vrooman.

In addition to the murder charge, Campbell was also found guilty of two counts of attempted second-degree murder, two counts of employing a firearm during the commission of a dangerous felony, three counts of reckless endangerment, unlawful possession of marijuana with intent to sell, unlawful possession of marijuana with intent to deliver and possession of a firearm with intent to go armed during the commission of a dangerous felony.

Campbell’s attorney told WREG he plans on appealing the guilty verdict.

After the sentencing, Memphis Police Director Michael Rallings issued a statement saying, “Officer Martoiya Lang made the ultimate sacrifice while upholding the oath that she swore to do; protecting and serving to citizens of Memphis. Hopefully, today’s events represents closure for Officer Lang’s family. The men and women of the Memphis Police Department will continue to honor Officer Lang through its dedicated service to the citizens of Memphis.”
