SPRINGFIELD, MI - A Facebook threat of a school shooting prompted a lockdown Friday at Springfield Middle School before investigators realized the message was meant for a school by the same name in Ohio, authorities said.

"After careful research by the Calhoun County Sheriff's Office, it was confirmed that the threat was actually meant for the Springfield Middle School in Holland, Ohio," investigators said in a news release.

"Better close school tomorrow im gonna kill everybody I promise especially (name) and his bald headed (expletive)," the Facebook threat said, according to a photo provided by the sheriff's office. "I swear to (expletive) god if you go to Springfield middle school shooting it up tomorrow watch."

Investigators said Calhoun County sheriff's deputies responded to school after learning of the threat and found that the facility was on lockdown.

"After a thorough investigation, it was determined that there was no threat to the school or the community of Springfield, Michigan," investigators said in the news release.
