ALPENA – Alpena High School officials acted quickly when a student used threatening language at the school on Friday morning, school officials reported.

An email sent to all Alpena Public Schools families at about 3 p.m. Friday said school officials and the school resource officer were alerted to the threat shortly after first hour.

The student was immediately removed from the classroom, moved to a secure location under the eye of law enforcement, and then removed from the school building pending ongoing investigation, according to Lee Fitzpatrick, APS director of communications.

The email did not specify the nature or circumstances of the threat. In a phone interview, Fitzpatrick would not say whether the threat involved any weapon.

Though the incident was limited to Alpena High School and not related to any other district building, the email was sent to all district parents to provide transparency and keep parents informed about the district as a whole, Fitzpatrick told The News.

In a follow-up email sent about half an hour after the first, Fitzpatrick clarified that a line in the original email containing the name of the recipient parents’ child did not indicate that child’s involvement in the incident. Student names are added automatically to emails sent through the district’s database, Fitzpatrick said.

Fitzpatrick would not say who told administrators about the threatening language, saying he did not want to discourage anyone from following the example of the person “who was brave and wise enough to let us know” what they had heard.

The email to parents included a reminder that the district “will prosecute to the fullest extent of the law anyone associated with school violence, threats of school violence, or the malicious destruction of school property.”

In December, students missed two days of school because of alleged gun-related threats reported to Alpena High School and Thunder Bay Junior High School administrators.

Alpena County Prosecutor Cynthia Muszynski has reports of police investigations of those incidents and will decide whether to request criminal charges.
