Two men have been charged with murder over the shooting at the Kansas City Chiefs Super Bowl parade which left one person dead and 22 wounded, officials said Tuesday.

Dominic Miller and Lyndell Mays, both local residents, were charged with second-degree murder, armed criminal action and unlawful use of a weapon, Jackson County Prosecutor Jean Peters Baker told reporters.

Peters Baker said Mays got into a verbal altercation with other individuals at the parade that “very quickly escalated.”

She said Miller allegedly fired the shots that killed a local DJ, Lisa Lopez-Galvan.

Peters Baker said both men were being held on $1 million bond and face a potential sentence of life in prison on the murder charges.

The prosecutor said the arrests of Miller and Mays were in addition to those of two juveniles whose arrests were announced last week.

The pair, who were not identified because of their ages, are facing gun-related charges and are accused of resisting arrest.

The shooting took place on Wednesday at the victory parade which had attracted up to a million fans to downtown Kansas City.

The Chiefs were celebrating their third Super Bowl title in five seasons after beating the San Francisco 49ers in Las Vegas on Sunday.

Mass shootings are common in the United States, where there are more guns than people and about a third of adults own a firearm.

President Joe Biden deplored the shooting and issued a rallying call for Americans to back his pleas for Congress to enact gun reform.
