An 18-year-old student faces a criminal charge after allegedly threatening multiple classmates and “talking about shooting up” his school, 9Wants to Know has learned.

Mitchell Meehan, a student at Endeavor Academy in the Cherry Creek School District, faces a misdemeanor charge of “interference with a school – credible threat” following his arrest Feb. 21.

He was taken into custody that morning at the alternative high school, according to court documents.

No one answered the door at Meehan’s Aurora home on Thursday. An attorney assigned to represent him did not return a message left at his office.

According to an arrest affidavit obtained by 9Wants to Know, school administrators reported concerns about Meehan on Feb. 15 – the day after a former student is accused of opening fire at a Florida high school, where 17 people were killed and another 17 were wounded.

Deputies were told by two students that they were riding a bus with Meehan when they heard him talk about guns. A student also said that Meehan repeatedly posted messages on a social media website saying “that he was going to shoot up the school.”

In an exchange with two students, Mitchell allegedly “threatened to shoot them both.”

Although the students told officers they were not sure whether Meehan was serious or that they thought he was joking, authorities took the threats seriously. Investigators confirmed that Mitchell owned guns, and even though there was nothing illegal about that they concluded the threats were serious enough to file a charge.

“Mitchell threatened to shoot two students on a school bus,” a deputy wrote in the affidavit. “Mitchell is known to own guns and sell them. Mitchell told the students that he was not joking when he made the threats.”

Prosecutors successfully argued to raise Meehan’s bail from the standard $750 to $100,000.

He is scheduled to be in court March 23.
