Lead #3Were there any witnesses to either shooting who could provide descriptions of the shooter or vehicle involved?
On May 18, 2015, 47-year-old John Jacoby was fatally shot twice while riding his bicycle on Weld County Road 15 near Windsor, Colorado—a brazen daylight attack by an unknown assailant that remains unsolved nearly a decade later. The case is believed connected to an April 22, 2015 shooting in Fort Collins where a female driver was shot in the neck, suggesting a possible pattern of violence by the same perpetrator. With a $50,000 reward offered, investigators are seeking any information that could identify the shooter and bring closure to this community that knew Jacoby as a dedicated local who worked in parks and recreation.
