The Kansas City Chiefs victory parade and rally on Wednesday, Feb. 14 quickly went from a joyful celebration to a terrifying and heartbreaking event when a mass shooting occurred that killed one person and left 22 others injured, including 11 children.

Two men have been charged with murder from this shooting. Missouri prosecutors said at a news conference that Lyndell Mays, of Raytown, Mo., and Dominic Miller, of Kansas City, Mo., have been charged with second-degree murder and several weapons counts.

The incident started when two groups grew agitated because they believed that the members of the other group were staring at them, police say.

This led to a confrontation using guns and ultimately, it had life-ending consequences.

Lisa Lopez-Galvan, the victim that was killed, attended the rally to celebrate the Chiefs Super Bowl win like many Kansas Citians that day. She was a mother of two and the host of a radio program called “Taste of Tejano” on KKFI-FM. She was remembered during her funeral service as a loving wife and mother whose smile could light up a room and who saw each day as a chance for excitement and laughter.

Authorities have also detained two juveniles on gun-related and resisting arrest charges. Jackson County prosecutor Jean Peters Baker said in a news conference that more charges are possible.

“I do want you to understand: We seek to hold every shooter accountable for their actions on that day. Every single one,” Peters Baker said. “So while we’re not there yet on every single individual, we’re going to get there.”
