By October 11, investigators had conducted 124 interviews and had found 174 pieces of evidence related to the case. They were also investigating the West Nickel Mines School shooting in Pennsylvania, which had occurred five days after the shooting in Bailey. As a result of the September 27 incident, Platte Canyon High School increased its security, leaving only one school entrance unlocked. It plans to install more security cameras. Park County Sheriff Fred Wegener proposed having a guard there during the school day, but he stated that that particular suggestion was outside the current budget.
