The two 16-year-old boys and a 17-year-old buy each were each charged with 17 counts of inducing panic in the second degree, two misdemeanor counts of telecommunications harassment and one count of possession of criminal tools, according to ClevelandJewishNews.com.
The 17-year-old boy, who has been expelled from Orange High School since the incident, pleaded guilty to seven counts of inducing panic and one count of possession of criminal tools. He is scheduled for sentencing in the Cuyahoga County Juvenile Court in August, according to Cleveland.com.
The two other suspects are scheduled for trial in late September. The maximum sentence is detention in a juvenile facility until they turn 21. All three were released to their parents.
Orange High School was closed for three days in November after school officials received a series of threatening emails. No explosives or biological material were found.
Local police and the Federal Bureau of Investigation gathered enough information to obtain a search warrant for the home of one of the suspects, who admitted to taking part in the crimes when investigators arrived.
The Orange School District offered little comment after the guilty plea was entered, other than to acknowledge that it continued to cooperate fully with law enforcement officials.
Orange Schools Superintendent Nancy Wingerbach said the entire experience has carried an important lesson with it.
“We learned that officials and parents must be aware of how our children use the technology available to them,” she said, Cleveland.com reports. “Their messages were routed around the world before sent to us, making them very hard to track back. Even the FBI had a hard time doing it. Kids are getting more sophisticated than adults in the use of modern technology, and we need to be aware of that.”
