KANSAS CITY, Mo. -- One person is dead, and 10 to 15 people were injured after shots were fired at the end of the Chiefs' Super Bowl parade Wednesday, Kansas City Police Chief Stacey Graves said.

Two people were taken into custody, Graves said during a news conference Wednesday afternoon.

"I'm angry at what happened today. The people who came to this celebration should expect a safe environment." she said.

According to ABC News, citing fire department officials, three of the injured are in critical condition, five are in serious condition and one person has non-life-threatening injuries. The condition of others injured wasn't immediately known.

Chiefs trainer Rick Burkholder said he was with coach Andy Reid and other coaches and staff members and that the team was on buses and returning to Arrowhead Stadium. Kansas City Mayor Quinton Lucas said all the team's players, coaches and staff are accounted for.

"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.

Social media users posted shocking video. One user's 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 down and tackle someone, holding that person down until two police officers arrived.

Lisa Augustine, spokesperson for Children's Mercy Kansas City, said the hospital "is receiving patients from the rally." She didn't know how many or immediately offer any details about their injuries.

St. Luke's Hospital of Kansas City received one gunshot patient in critical condition and one walk-in patient with injuries that were not life threatening, spokesperson Laurel Gifford said.

The University of Kansas Health System was treating one person wounded in the shooting, said Jill Jensen Chadwick, news director for the health system. She didn't know the person's condition.

"When you have this many casualties, it's going to get spread out among a lot of hospitals so that you don't overwhelm a single ER," she said.

Missouri Gov. Mike Parson and the first lady were at the parade when shots were fired but are safe, Parson posted on X.

"State law enforcement personnel are assisting local authorities in response efforts," Parson posted. "As we wait to learn more, our hearts go out to the victims."

Multiple Chiefs players took to social media to express their concern for the victims after the shooting.

Chiefs quarterback Patrick Mahomes posted on X, "Praying for Kansas City...," also including three emojis of hands in prayer.

Chiefs linebacker Drue Tranquill posted on X, "Please join me in prayer for all the victims in this heinous act. Pray that doctors & first responders would have steady hands & that all would experience full healing."

Offensive lineman Trey Smith posted to X, "My thoughts and prayers are with everyone affected by today's incidents -- a huge thank you to the first responders who ran towards the sound of danger. You're the ones who should be celebrated today."

The shooting broke the celebratory mood on Valentine's Day as Chiefs fans marked their third Super Bowl title in five seasons.

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.
