timeline
Lead #3Why was there a 26-day gap between the Fort Collins shooting and the Jacoby murder—was the shooter inactive or targeting specific individuals?
On May 18, 2015, 47-year-old John Jacoby was fatally shot twice while riding his bicycle on Weld County Road 15 north of Windsor, Colorado. The shooting is believed connected to an April 22, 2015 incident in Fort Collins where a female driver was shot in the neck and survived. Despite a $50,000 reward and FBI involvement, the identity of the shooter or shooters remains unknown, leaving critical questions about motive and whether these attacks are part of a larger pattern.
