Two juveniles have been charged with crimes connected to the shooting at the Kansas City Chiefs' Super Bowl rally, authorities said on Friday.

A news release from the Jackson County Family Court said the juveniles are being detained in the county's Juvenile Detention Center “on gun-related and resisting arrest charges.”

The release said it is “anticipated that additional charges are expected in the future as the investigation by the Kansas City Police Department continues.”

No further information was released.

A mother of two was killed and 22 people were injured by gunfire Wednesday afternoon, when shots erupted amid the throng of fans gathered at a rally outside Union Station after a parade through the city. Police Chief Stacey Graves said Thursday that victims ranged from ages 8 to 47, with half under 16.

Police initially detained three juveniles but released one who they determined wasn't involved in the shooting. Police are looking for others who may have been involved and are calling for witnesses, victims and people with cellphone video of the violence to call a dedicated hotline.

The shooting outside Union Station occurred despite the presence of more than 800 police officers who were in the building and surrounding area, including on top of nearby structures, said Mayor Quinton Lucas, who attended with his wife and mother and ran for safety when the shots were fired. But he doesn't expect to cancel the upcoming St. Patrick's Day parade.

“We have parades all the time. I don't think they'll end. Certainly we recognised the public safety challenges and issues that relate to them,” Lucas said.

Wednesday's celebration was the third such parade since 2020, and the others had no violence. People packed the parade route, with fans climbing trees and street poles for a better view. Players rolled through on double-decker buses as DJs and drummers heralded their arrival.

The rally had just ended and music was still blaring when the shots began. Many people initially thought they were hearing fireworks. Some in the crowd hit the ground while others leapt over barriers and sprinted, some carrying children in their arms.

Eventually stunned rallygoers — many in tears — gathered their belongings, trying to figure out how to get home. Strangers comforted each other as police put up crime scene tape where moments earlier there had been a joyous celebration.

The police chief said 1 million people likely attended the parade, which occurred in a city of about 470,000 people and a metropolitan area of about 2 million, but stressed that the violence was wrought by just a handful of people.

“The law enforcement response was exemplary. Those in attendance also responded," Graves added.

Among them was Trey Filter, who was walking to the car with his family when he heard yells of “get him.”

Filter, 40, who lives outside Wichita, Kansas, saw a fleeing person, prompting him and another bystander to try to tackle him. Filter eventually jumped on top of the person.

“I don't know what the hell I was thinking,” the owner of an asphalt and concrete company recalled. “We was like, We got him.' I'll always remember that. And then they started screaming, 'There's a gun!'”

The gun fell near his wife, Casey Filter, who picked it up. At that point the fleeing person was under a dogpile about 10 feet (3 meters) away.

Police didn't identify Filter as a man who intervened or specifically say whether the person he tackled was a suspect.

Hank Hunter, a Kansas high school sophomore, said he heard shots in the distance while watching the rally with a friend. Initially, they didn't know what it was, but then, “like a chain reaction,” people started hitting the ground.

They ran to jump over a barricade, and his friend slammed his head into the concrete, Hunter said. A security guard ushered his friend into Union Station, which was closed to the general public, as the Chiefs players and coaches prepared to leave on buses. There, coach Andy Reid consoled his friend and “just tried to comfort him and calm him down.”

The slain woman was identified by radio station KKFI-FM as Lisa Lopez-Galvan, host of “Taste of Tejano.”

Lopez-Galvan, whose DJ name was “Lisa G,” was an extrovert and devoted mother from a prominent Latino family in the area, said Rosa Izurieta and Martha Ramirez, two childhood friends who worked with her at a staffing company.

Taylor Swift, who is dating Chiefs tight end Travis Kelce, donated USD 100,000 to Lopez-Galvan's family through GoFundMe campaigns.

Kansas City has long struggled with gun violence, and in 2020 it was among nine cities targeted by the US Justice Department in an effort to crack down on violent crime. In 2023, the city matched a record with 182 homicides, most of which involved guns.

Lucas has joined with mayors across the country in calling for new laws to reduce gun violence, including mandating universal background checks.
