Ewing police say Michigan State gunman Anthony McCrae had a note in his pocket indicating a threat to two Ewing schools: Ewing High School and Fisher Middle School.

They say further investigation determined the shooting was isolated to Michigan and there was no threat to Ewing. 

The threat closed all public schools in Ewing Township early Tuesday morning. Officers remained at all Ewing schools for the day but a normal schedule is anticipated for Wednesday, Feb. 15.

The Ewing Police Department posted a message on Facebook and said the action was done out of an abundance of caution.

"All Ewing public schools are closed today while we investigate an unconfirmed school threat,” the post said. “Additional officers from Ewing and partner agencies will be deployed to all Ewing public and private schools. The safety and security of our students is always paramount. Please do not call the police department seeking information."

Ewing police later updated the Facebook page, and said the police department received assistance from partner agencies to provide security to all of the schools in Ewing.

"This plan is in place throughout the county to quickly add additional law enforcement resources when needed," the post said. "The additional resources will remain in place as a precaution as we continue our investigation.”
