Police arrest 19-year-old for shooting death of officer

Biloxi, MS-Police arrested 19-year-old man for the shooting death of a Mississippi police officer.

Biloxi Police Chief John Miller said Darian Tawan Atkinson was arrested Monday night for allegedly killing Biloxi police officer Robert McKeithen in the parking lot of police headquarters the night previous.

"It's been a long couple of days," Miller said in a press conference Monday night that was broadcasted on the Gulf Port Police Department's Twitter page. "We feel vindicated. He's been treated proper. Fair. Now we grieve for the family."

Atkinson was charged with capital homicide of a law enforcement officer following Sunday's fatal shooting of McKeithen, a 24-year police veteran who was to retire at the end of the year.

McKeithen was shot multiple times shortly after 10 p.m. during what police described as an ambush. The motive is still unknown.

Atkinson was arrested in the city of Wiggins after he was spotted by a police officer who was heading home, Miller said.

He was smiling while being escorted under a heavy police presence into Biloxi police headquarters.

"Oh, the police are mad at me," he said.
