Defendant Treveno Campbell, 25, also was convicted of the attempted second-degree murder of two other officers, employing a firearm during the commission of a dangerous felony, three counts of reckless endangerment, and felony drug charges.
The Criminal Court jury returned its verdict following a nine-day trial. Campbell faces up to 25 years on the murder conviction and up to 12 years on each of the attempted murder convictions.
He remains in custody and will be sentenced March 1 by Judge James Beasley Jr.
“It has been a long time coming, but justice finally has been served, and the family of Officer Lang can have some closure,” said Gen. Weirich. “I am grateful for the long, hard work of our prosecutors, Alanda Dwyer and Reginald Henderson, and staff, our witnesses and for the diligent efforts of the jury.”
The shooting occurred Dec. 14, 2012, when members of the Memphis Police Department’s Organized Crime Unit were executing a search warrant for drugs at 1062 Mendenhall Cove in the Berclair area of northeast Memphis.
After entering the residence, officers began placing one suspect in custody when another suspect, Campbell, fired shots from a bedroom, striking Lang and killing her. Another OCU officer, William Vrooman, was shot and wounded.
Officers returned fire, striking and wounding Campbell, who recovered from his injuries.
Asst. Dist. Atty. Dwyer is chief prosecutor of the DA’s Special Prosecution Unit (SPU.) Prosecutor Henderson is the DA administrative assistant. The SPU seeks maximum punishment for repeat felony offenders.
