A 14-year-old Ottawa school district student is in custody following alleged threats made against the high school.

Dr. Ryan Cobbs, assistant superintendent, said the district took the threat very seriously and worked with the Ottawa Police Department which responded to the threat and placed the suspect in custody.

The threats were reportedly made Friday afternoon on a school bus and the bus driver reported it to the district.

“We take threats very seriously,” Cobbs said. He added that following an incident like this the safety plan will be reviewed with each building.

Adam Weingartner, Ottawa assistant police chief, said the school resource officer was notified and officers were sent to investigate.

“Any type of threat has to be taken seriously and investigated thoroughly,” he said.

Additional details about the threat were unavailable.

Dr. Jeanne Stroh, superintendent, said that the district utilizes A.L.I.C.E training and each building will go through the training three times this year. It stands for Alert, Lockdown, Inform, Counter and Evacuate.

“The safety of our students is our number one priority,” Stroh said.

She added that construction at the high school has created some challenges but staff has worked together to ensure the safety of students.

Stroh sent a letter Sunday to make parents and staff aware of the threat. In the letter she urged everyone to use this event to have a conversation about suspicious behavior.

“This provides us with the opportunity to remind staff, parents, and grandparents to have discussions with their children about reporting any possible suspicious activity or behavior to school administration and/or law enforcement,” the letter said. “It is only with your help and concern that we become aware of potential safety concerns so proper action can be taken to protect our students and staff.”

The student was still in custody as of Monday, and Weingartner said the threat was still under investigation but no other arrests were expected.

The threat was made just more than a week after a 19-year-old gunman killed 17 and wounded 14 at Marjory Stoneman Douglas High School in Parkland, Florida.
