VIENNA — A Columbiana County man on Wednesday was no billed, meaning not indicted, by a Trumbull County grand jury on four felony charges connected to threats made to a Vienna aeronautics school in May.

Christian Blymiller, 18, of Waterford Road, New Waterford, faced two counts of making terroristic threats and two counts of inducing panic. All the charges were dropped on Wednesday when the grand jury chose not to indict him. Trumbull County jail records show Blymiller was released from lockup at 2:21 p.m. Wednesday.

The case was linked to a May 25 incident when a teacher from the Pittsburgh Institute of Aeronautics called Trumbull County 911 shortly before 4 p.m. to report a threat was made earlier at the school, and a pawnbroker in Youngstown reported a man had picked up a firearm and was headed to the Vienna location.

The teacher reported the man threatened to shoot up the school and had purchased an AR-15, the man said he was headed to the school located at the Youngstown-Warren Regional Airport.

According to the 911 report, the nearby air reserve station was notified, and all faculty, staff and students were escorted off the school property by 4:10 p.m. Authorities tried to ping the man’s cellphone to get his location. Police also tried to contact Blymiller’s parents to see if they could reach him.

According to the 911 report, Blymiller agreed to cooperate with authorities, and any guns were locked up in a safe, according to Blymiller’s father.

Blymiller reportedly gave himself up to Columbiana police at a truck stop about 90 minutes after the reports. The weapon was secured as evidence with the help of the Ohio State Highway Patrol, a report states.

Assistant Prosecutor Charles Morrow said he could not comment further on the case against Blymiller.
