Deputies responded quickly and located the suspect, later identified as Yonic Mendoza-Sanchez (DOB 05/15/04) of Fort Collins. As law enforcement arrived, Mendoza-Sanchez descended from the roof and briefly disappeared from view. He was safely taken into custody minutes later in a nearby area.

Deputies determined the suspect had no connection to the residence. After entering the home to ensure no one inside was harmed, they found one adult female resident uninjured. Investigators discovered that Mendoza-Sanchez had broken into the house, stolen a shotgun, and climbed to the roof, possibly firing one round during the incident.

The shotgun was recovered inside the home. Thankfully, no injuries have been reported.

  • Criminal Mischief – $1,000 to < $2,000 in Private Property Damage (M1)
