Beaver Dam public schools will reopen today (Monday) with an added police presence. Schools were closed on Friday after an associate high school principal found emails that threatened the safety of both students and staffers at the school. Police said they were able to talk with two boys on Friday morning about the threats, and a third boy who was reportedly involved was reached in Las Vegas. By late Friday, officials were saying that all three boys were cooperating with law enforcement and any resulting threats have been eliminated.
