Two juveniles were charged in connection with a shooting that left one person dead and 22 wounded at a parade celebrating the Kansas City Chiefs Super Bowl victory, police said Friday.

The two face charges of "gun-related and resisting arrest charges." Authorities said "additional charges are expected in the future as the investigation by the Kansas City Police Department continues.”

The two are being held in the Jackson County Juvenile Detention Center, according to Jackson County Family Court.

The shooting broke out around 2 p.m. Wednesday in the midst of the crowd of more than 1 million people gathered for the celebration in front of Kansas City's Union Station. The violence left 22 people aged 8-47 suffering from gunshot wounds and killed Lisa Lopez-Galvan, a beloved mother of two and local DJ.

Police released other person they'd detained after authorities determined they were not involved, Kansas City police officer Alayna Gonzalez told USA TODAY. Gonzalez said officers are working with juvenile prosecutors to “review investigative findings and determine applicable charges."

More than 800 security and law enforcement personnel were present at the parade. Officials recovered several weapons after the shooting.

Videos of the shooting posted to social media showed parade attendees scatter and chaos descend on the crowd after shots rang out. One video captured a group of people tackling a person to the ground. Graves said the person who was tackled was detained by police, but did not disclose whether they are one of the two people charged.

Under Missouri law, juvenile court records for misdemeanor offenses are usually kept private, while records of felony offenses can be unsealed, according to the Missouri public defender's website.

Police believe the shooting was triggered by a personal dispute, but have not released further information on the motive behind the shooting.

Nine children with gunshot wounds were admitted to Children's Mercy Hospital after the shooting, Stephanie Meyer, the hospital's chief nursing officer, said at a Thursday news conference. Three children still being treated are expected to fully recover, she said.

Two victims of the shooting in treatment at another Kansas City hospital are in critical condition, but are both improving, trauma surgeon Dr. Dustin Neel said Thursday. Five people were released from the hospital as of Thursday.
