The shooting at the Kansas City Chiefs Super Bowl victory rally was not a case of terrorism or homegrown violent extremism, authorities said Thursday.
“This appeared to be a dispute between several people that ended in gunfire," said Kansas City Police Chief Stacey Graves.
Three people were initially detained, but police said one person was released and two juveniles are still in custody.
"This is still under investigation," she added. "We do have 24 hours until we have to either file charges or release them."
The shooting left one person dead and more than 20 others injured, including children.
Children’s Mercy received 12 patients from the rally on Wednesday. Nine of the children had been shot, officials said. All but three of the children have been released from the hospital. However, officials believe they will recover.
A spokesperson with University Health Truman told Scripps News Kansas City that two people, presumably adults, remained in critical condition. Another patient at Saint Luke's Hospital is reportedly in critical condition.
Lisa Lopez-Galvan was identified as the woman who died. She was a DJ at a local radio station in Kansas City.

The shooting happened as the parade rally, which was reportedly attended by nearly 1 million people, was concluding.
Video shared on social media showed at least one of the possible suspects being tackled by a group of people who kept the person on the ground until police arrived.
Trey Filter said his wife Casey grabbed the suspect's gun as he helped restrain him.
"Once I picked it up I realized it was a real gun and so I just moved it," she said. "Honestly, it was just a reaction. I didn't feel like I needed to run away. I saw my husband subduing the guy and then my kids, I was worried about where my kids were. It was just a very chaotic moment."
