The Associated Press reported on Thursday that authorities in Kansas City revealed that the mass shooting during the Chiefs' Super Bowl celebration was likely a result of a dispute between several individuals.
Police Chief Stacey Graves said that the 22 individuals injured in the shooting ranged between the ages of 8 and 47 years old, with half under the age of 16. A mother of two was also fatally shot.
The mother killed in the shooting was identified Wednesday by radio station KKFI-FM as Lopez-Galvan, host of "Taste of Tejano."
Three people were detained, two of whom were juveniles. Firearms from the scene were recovered during the chaos, police said.
"We are working to determine the involvement of others. And it should be noted we have recovered several firearms. This incident is still a very active investigation," Graves said at a news conference.
The shooting occurred at Union Station despite the presence of more than 800 police officers. Authorities were spread out in the building and around the premises, including on top of nearby structures, said Mayor Quinton Lucas.
Lucas attended the event with his wife and mother and ran for safety when the shots rang out.
He is not expected to cancel the upcoming St. Patrick's Day parade despite this tragic incident.
ESPN reported Fire Chief Ross Grundyson confirmed that the victims included eight critically hurt and seven in serious condition.
It's unclear exactly how many people attended the Chief's Super Bowl parade. An estimated 800,000 people participated in the victory parade when the Kansas City Royals won the World Series in 2015. In a city with a population of about 470,000 and a metropolitan area of about 2 million, expectations can be easily shattered.
Witnesses described confusion as gunshots rang out, initially mistakingly them as fireworks.
Rally music continued playing despite the chaos, however, moments after the shooting stopped, there were reports of people walking on as if nothing happened.
Social media users posted videos of police running through the crowded scene. One showed someone performing chest compressions on a victim as another person, seemingly writhing in pain, lay on the ground nearby. People can be heard screaming in the background.
An explanation behind the motive remains unclear.
Investigators are calling for witnesses, people with cellphone footage, and victims of the violence to call a dedicated hotline.
