PHOENIX — A man wanted in connection with a homicide in North Carolina has been arrested in southern Arizona.

Arizona Department of Public Safety officials say 42-year-old Christopher Paul Huffman was taken into custody Monday on Interstate 10 near Casa Grande.

They said Huffman was wanted in the fatal shooting of 62-year-old Charles Michael Middleton last Friday at the victim's home in Charlotte.

North Carolina authorities said the two men knew each other, but a motive for the shooting isn't immediately clear.

An Arizona Highway Patrol officer pulled over Huffman after confirming the vehicle he was driving was connected to the homicide case.

DPS officials said a stolen handgun also was found inside the vehicle.

They said Charlotte-Mecklenburg detectives were flying to Arizona on Tuesday to interview Huffman and process the vehicle.
