Champaign County deputies have alleged Serna also shot at a teacher and then randomly shot at classrooms before he was detained by school staff members. Another student was grazed by a shotgun pellet but not injured.

Serna has been charged with several felonies — two counts of attempted murder, three counts of felonious assault, six counts of improperly discharging a firearm, and single counts of inducing panic and illegal conveyance of a deadly weapon in a school. He’s pleaded not guilty by reason of insanity.
The defense has filed motions to suppress evidence in the case and to move it back into juvenile court.

In the motion to move the case back, defense attorney Dennis Lieberman argues proper procedure wasn’t followed before Champaign County Juvenile Judge Lori Reisinger ordered the transfer to adult court. Serna had waived his right to a probable cause hearing but did ask for an amenability hearing, according to the motion.
