A popular triathlon in northern Colorado has been canceled following a rash of shootings near the small town of Windsor, which has left one person dead and another injured.

John Jacoby, 48, was shot dead earlier this week while cycling along a stretch of road just outside of Windsor, reports ABC News. The incident occurred in close proximity to an earlier shooting late last month, when a 20-year-old woman survived being shot in the neck while driving along Interstate 25 outside of nearby Fort Collins.

Local officials are working in tandem with federal investigators, who are scrambling to see if the two events are connected. In the wake of the shootings, organizers of Pelican Fest Sprint Triathlon have canceled the race slated for this weekend because of security concerns.

“My decision was based on the overall safety of all the athletes, volunteers, traffic control personnel, spectators and vendors,” wrote Dennis Vanderheiden, the race’s director, in a post published online. “The proximity of the shooting death and the bike course gave me real concerns.”
