Eight children were among 22 people hit by gunfire in a shooting at the end of Wednesday's parade to celebrate the Kansas City Chiefs Super Bowl win, authorities said, as terrified fans ran for cover and yet another high-profile public event was marred by gun violence. One person was killed. Kansas City Police Chief Stacey Graves detailed the shooting's toll at a news conference and said three people had been taken into custody. She said she has heard that fans may have been involved in apprehending a suspect but couldn’t immediately confirm that. "I’m angry at what happened today. The people who came to this celebration should expect a safe environment." Graves said. Police did not immediately release any details about the people taken into custody or about a possible motive for the shootings. It is the latest sports celebration in the U.S. marred by gun violence, following a shooting last year in downtown Denver after the Nuggets' winning an NBA championship that injured several people, and gunfire last year at a parking lot near the Texas Rangers' World Series championship parade. Social media users posted shocking video of police running through a crowded scene as people in attendance hurriedly scrambled for cover and ran away. One video showed someone apparently performing chest compressions on a shooting victim as another person, seemingly writhing in pain, lay on the ground nearby. People screamed in the background. Another video showed two onlookers chase and tackle someone, holding that person down until two police officers arrived. Kansas City has long struggled with gun violence, and in 2020 it was among nine cities targeted by the U.S. 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. Mayor Quinton Lucas has joined with mayors across the country in calling for new laws to reduce gun violence, including mandating universal background checks. Lucas, who attended the celebration with his wife and mother, said he was heartbroken and angry. “This is absolutely a tragedy, the likes of which we never would have expected in Kansas City, the likes of which we'll remember for some time,” Lucas said. Missouri’s Republican Gov. Mike Parson and First Lady Teresa Parson were at the parade during the gunfire but were unhurt. “Thanks to the professionalism of our security officers and first responders, Teresa and I and our staff are safe and secure,” Parson said in a statement. President Joe Biden has been briefed on the shooting in Kansas City and will continue to receive updates, a White House spokesperson said. White House officials have been in touch with state and local leaders, and federal law enforcement is on the scene supporting local law enforcement. Areas that had been filled with crowds were empty after the shooting, with police and firefighters standing and talking behind an area restricted by yellow tape. Throngs had lined the route, with fans climbing trees and street poles, or standing on rooftops for a better view. Players rolled through the crowd on double-decker buses, DJs and drummers heralding their arrival. Owner Clark Hunt was on one of those buses, holding the Lombardi Trophy. The city and the team each chipped in around $1 million for the event commemorating Travis Kelce, Mahomes and the Chiefs becoming the first team since Tom Brady and the New England Patriots two decades ago to defend their title. After decades without a championship, the city is gaining experience with victory parades. Five seasons ago, the Chiefs defeated the 49ers for the team’s first Super Bowl championship in 50 years. That followed the Kansas City Royals winning the World Series in 2015, the city’s first baseball championship in 30 years. That year, fans abandoned their cars on the side of the highway so they could walk to the celebration. Then, last year, the Chiefs defeated the Philadelphia Eagles 38-35 and prophetically vowed they would be back for more.
