Kansas City police say that the mass shooting that left one person dead and 22 injured at the Chiefs' Super Bowl parade appeared to have stemmed from a dispute among several people.

Police Chief Stacey Graves said that the 22 people injured in the shooting ranged between the ages of 8 and 47 years old and that half of the injured were under the age of 16.

An adult who had been detained has been released from custody, police spokesperson Alayna Gonzalez told multiple media outlets Thursday. That leaves two juveniles detained.

"The two juveniles are currently being held in custody while we work with juvenile prosecutors to review investigative findings and determine applicable charges," Gonzalez said.
