The El Paso County Sheriff's Office is investigating reports of a man threatening mountain bikers with a hatchet in the same area north of the Air Force Academy where a cyclist, Timothy Watkins, of Palmer Lake, was killed. Both incidents happened over the weekend near Mount Herman Road west of Monument. The Sheriff's Office would not say if they believe the crimes are related. "Things have happened in that area that are a public safety concern, but we also don't want to prohibit people from doing the activities they love and they actually come to Colorado for," sheriff's spokeswoman Jacqueline Kirby told Gazette news partner KKTV.
