Patrick Mahomes and the Kansas City Chiefs were celebrating today with thousands of fans in a spectacular Super Bowl parade after their win against the San Francisco 49ers.

However, at the conclusion of the rally, crowds started to run desperately when they heard many shots were fired west of Union Station near a garage. Police confirmed at least one person was killed and 21 others were injured at the site. Three are in critical condition.

Furthermore, three people were already taken into custody after a tragic day for the city and the NFL champions. “At this time, we have confirmed that all of our players, coaches, staff and their families are safe and accounted for. We thank the local law enforcement officers and first responders who were on scene to assist.”

What happened at Chiefs’ Super Bowl rally?

Players and coaching staff were celebrating on stage when, in the final part of the parade, thousands of people started to run and scream when they heard the detonations near Union Station.

According to different interviews with witnesses, most of the fans thought the detonations were fireworks to close the celebrations of the parade. Then, when people started to scream, chaos unfolded.

FS1 was broadcasting ‘First Things First‘ on site, but, when the news broke, they stopped immediately to guarantee the safety of the crew. This was the message by Nick Wright. “The entire FS1 team at the parade in KC is safe and accounted for. I’m absolutely heartbroken for everyone that this happened.”
