A news release from the Solicitor's Office does not say why Helms is making the appearance in General Sessions Court.
In March, Family Court Judge Georgia Anderson decided that Helms would be tried as an adult for the charges he faces, including attempted murder, two counts of possession of an incendiary device and two counts of attempted detonation of those devices.Related Stories Socastee teen to be tried as an adult Socastee school shooting hearing continues Teen arrested after shot fired at Socastee High School
Helms is accused of firing a shot that narrowly missed Horry County Officer Erik Karney at Socastee High School last September and bringing pipe bombs to school that day in his book bag.
Since the March decision, Helms has remained at the Department of Juvenile Justice in Columbia, where he's been treated for mental health issues.
At the time the decision was made to try Helms as an adult, his defense attorney, Russell Long, said Helms would most likely plead guilty in adult court and work out a sentence with the Solicitor's Office. Wednesday's court appearance could see that plea made.
