The Delaware County Sheriff’s Office says a report of a threat against Downsville Central School on Friday was found to be not credible. According to the sheriff’s office a parent notified them of the possible threat after seeing it on social media Thursday night. An investigation led deputies to a 17 year old student who was interviewed and that resulted in the determination the threat wasn’t credible. The incident came just a day after a shooter at a Florida high school killed 17 people.
