Two adults were charged with murder Tuesday over the terrifying shooting at the Kansas City Chiefs Super Bowl parade that left one dead and 22 others hospitalized, prosecutors said.

Dominic Miller, 18, and Lyndell Mays, 22, both face charges of second-degree murder and two counts of armed criminal action and unlawful use of a weapon.

They are being held on $1 million bond.

“The defendants attended a Super Bowl parade and rally on Feb. 14, 2024, and were armed with firearms,” the Jackson County prosecutor’s office said.

“A verbal altercation occurred and gunfire broke out with no regard for thousands of other individuals in the area.”

Miller and Mays had “no prior connection” before they encountered one another at the parade on Valentine’s Day, prosecutors confirmed at a press conference, but when a heated argument broke out between the strangers, it quickly escalated.

Mays allegedly drew his weapon first, and “almost immediately” several others, including Miller, brandished their own.

It was Miller’s weapon that fired the bullet that killed 43-year-old Lisa Lopez Gavlan, a mother of two, prosecutors said.

The charges come just days after two teens were slapped with gun and resisting arrest charges.

Those teens were charged as minors, but officials have said they could be upgraded to adults in the coming weeks.

A total of four people have now been charged in the deadly mass shooting.

They declined to comment on how many shooters they suspected were involved.

The shooting broke out on Wednesday as thousands of fans lined the streets of Kansas City to watch NFL team’s victory parade.

The gunfire erupted over a dispute between the suspects, according to police, though the exact nature of the fight remains unclear.

Crowds scattered in a terrifying scene investigators called a “stampede” as the shots rang out, but brave bystanders managed to tackle the suspects as they fled.

The alleged gunmen were restrained on the ground by the citizens until police were able to detain them.

In addition to the fatal wounds Gavlan suffered, 12 children were injured in the hail of bullets.

One boy was struck with a bullet that missed his lungs by centimeters, with his family calling his survival a “miracle.”

He and the other children were all released from the hospital in stable condition as of Saturday.

Of the victims, ranging in age from 8 to 47 years old, one was left in critical condition and two were reported to be improving as of the weekend.

Both Miller and Mays have been in the hospital themselves since their arrest, though the nature of their injuries remains unclear.

Their relationship to the two minors charged also remains unclear.

Investigators said they have identified all bystanders who were struck by bullets in shooting but are asking anybody who suffered any other kind of injury in the ensuing stampede to come forward to assist their investigation.
