Eight months after a mass shooting at a DIY punk show in Minneapolis left one person dead and six others injured, a teenage suspect has been charged with seven felonies, including aiding and abetting second-degree intentional murder and six counts of felony assault with a firearm. The shooting is believed to have been motivated by bias against the victims’ gender, sexual orientation, gender identity, and gender expression. Investigators used DNA testing to identify the suspect, who appeared in juvenile court Tuesday afternoon.
