Model Laboratory School in Richmond has cancelled classes from Tuesday through Thursday because of threatening graffiti found at Eastern Kentucky University.
Model, on the EKU campus, has students from preschool through grade 12, and administrators decided to be extra cautious in light of that, said EKU spokeswoman Kristi Middleton.
The graffiti was reported early Monday, leading campus police to increase patrols and issue alerts to students and staff, but EKU classes have not been cancelled.
Middleton said some student activities have been rescheduled, but "our plan is to keep the university open."
Never miss a local story.
She said some faculty members have been considering ways to adjust their classes, but unless an arrangement has been worked out with the instructor, students are expected to be in class.
The writing was found on the wall of a bathroom in the Powell Building and stated, "KILL ALL BY 10/8/15 THIS BU OOP," according to a Facebook post by the EKU Police Department.
The Powell Building houses the university's student center, a dining hall and meeting rooms.
EKU police are offering a $10,000 reward for the identification, arrest and conviction of the person responsible for the threat.
Model already was scheduled to be closed Friday and next Monday and Tuesday for fall break. Students at Model will not be back in class until Wednesday, Oct. 14.
Middleton said some after-school activities were cancelled at Model Monday but that the school day otherwise continued as normal.
Police think the message was written on the wall at EKU late Sunday, according to the Facebook post.
The message comes just days after nine people were killed by a gunman at Umpqua Community College in Oregon.
