Police say an armed security guard shot and killed a man suspected of fatally shooting a woman and injuring 15 more people outside a nightclub in Kansas City, Missouri.  

Police say the shooting took place just before midnight, when someone opened fire on a line of people waiting outside 9ine Ultra Lounge. 

A man and a woman were found dead at the scene. Police believe the man was the shooter, who was shot by an armed security guard. 

A motive for the shooting has not been revealed. 

Kansas City Police Capt. David Jackson told reporters early Monday that responding officers found “a chaotic scene.”

The nightclub is located just four miles from Arrowhead Stadium, where the Kansas City Chiefs won the AFC Championship earlier in the day. 

At least 15 people arrived at local hospitals with injuries and three are in critical condition.
