Southern Oregon University closed its main campuses Wednesday and Eastern Kentucky University cancelled classes through the end of the week after threatening messages were found at both campuses Wednesday.

The Ashland Police Dept. tells Fox News SOU’s Ashland campus was closed after a threatening note was found in a bathroom on campus. Police Chief Tighe O'Meara says investigators will send forensic evidence to state police labs for further analysis.

Police also say they are “working together” with Campus Public Safety “on analyzing this potential threat.”

Ashland is located about 112 miles south of Roseburg, where a shooter killed nine people and wounded many more at Umpqua Community College on Thursday. The shooter later killed himself.

Eastern Kentucky cancelled classes for the rest of the week after menacing graffiti was found in a bathroom, according to the school's public safety office. A photo of the graffiti posted on social media showed large black letters scrawled on a white bathroom wall saying, “KILL ALL BY 10-8-15.”

Eastern Kentucky University's campus is located in Richmond. University President Michael Benson said Wednesday that the goal was to limit safety risks while assessing the threats.

"While we are confident the responding team of law enforcement agencies has kept a watchful eye over our community and is diligently investigating the threat, it has become clear this incident continues to be unsettling to a number of our students, faculty and staff," Benson said in a campus message.
