Two juveniles were charged with crimes connected to the mass shooting at the Kansas City Chiefs’ Super Bowl rally, authorities said Friday, as the city tries to recover in the aftermath of the violence.

A news release from the Jackson County Family Court said the juveniles were charged Thursday and are being detained in the county’s Juvenile Detention Center “on gun-related and resisting arrest charges.” The release said it is “anticipated that additional charges are expected in the future as the investigation by the Kansas City Police Department continues.”

No further information was released. Juvenile court cases are largely kept private under Missouri law, and hearings are not open to the public.

Police initially detained three juveniles but released one who they determined wasn’t involved in the shooting. Police are looking for others who may have been involved and are calling for witnesses, victims and people with cellphone video of the violence to call a dedicated hotline.
