Indiana manhunt intensifies for suspect in deadly Walmart shooting

Police in Indiana have identified an "armed and dangerous" suspect wanted following a fatal shooting at a Walmart parking lot in Fort Wayne. 

Micah Nunn, 20, is described by the Fort Wayne Police Department as a Black male around 6-feet 2-inches tall, weighing 240 pounds and having black hair and brown eyes. He is wanted for murder.

Investigators say the shooting unfolded around 11:40 a.m. Thursday at the Walmart Supercenter at Southtown Crossing, in the southern part of the city. 

"Preliminary investigation indicates that the victim, an adult male, was in a stopped vehicle when the suspect exited another vehicle, got into the vehicle the victim was in and shot the victim," police said in a statement. "The suspect then got back into the vehicle that they initially exited and fled the area."
