An argument among several people sparked the shooting that killed one woman and wounded 22 people in Kansas City Missouri after a celebration of the Kansas City Chiefs¡¯ Super Bowl victory, police said on Thursday, ruling out any apparent link to extremism.

Three people, including two minors, were detained as ¡°subjects¡± in the investigation, Stacey Graves, the Kansas City Police chief, said at a news conference the day after gunfire erupted in the vicinity of the city¡¯s historic downtown rail station.

The third detainee, also a juvenile who was determined not to be involved, was later released, according to police spokesperson Alayna Gonzalez.
