FORT WORTH, Texas (AP) - Fort Worth police have shot and killed a 18-year-old man who they say was a person of interest in a homicide investigation.

  

Sgt. Chris Daniels says preliminary information indicates that at least one officer shot the man around 5:45 p.m. Wednesday after he ran away and then "displayed" a handgun toward police.

  

A lawyer for his family identified the dead man as Amari Malone and disputed that he was armed.

  

Attorney Lee Merrit says three witnesses told him Malone did not have a gun and that security camera footage of the shooting offers no evidence that he pointed one at police. Merritt says Malone was black and shot once in the back.

  

Police have scheduled a Thursday afternoon news conference.
