A man was shot and killed Saturday in the Alexandria section of Fairfax County.
Authorities said they were called at about 8:50 p.m. by a neighbor who heard a disturbance and a gunshot in the 7400 block of Vernon Square Drive.
First responders found 23-year-old Raphael Pierce in an apartment with an apparent gunshot wound to the upper body, police said. He was pronounced dead on the scene.
Authorities believe that during a small gathering at the apartment, Pierce argued with 40-year-old Terence Butler for an unknown reason and Butler opened fire.
"Detectives believe Butler shot Pierce before leaving in a dark colored 2013 Chevrolet Impala bearing Virginia registration URH-1176. The Impala was described as having black rims and damage to the passenger side," police said in a news release.
Butler is wanted for second degree murder, use of a firearm in the commission of a felony and possession of a firearm by a convicted felon, police said.
Detectives said both men knew each other, but the full extent of their relationship is under investigation.
Anyone with information is asked to contact police at 703-691-2131 or 911. Butler should be considered armed and dangerous.
