Greeley police said an 18-year-old man has been arrested for allegedly having sex with a 12-year-old girl whose decomposed body was found this week.
Sgt. Joe Tymkowych says Robert Laurencio Montoya's arrest is unrelated to the homicide investigation involving Kayleah Wilson's death. Additional details were not immediately released.
Sixth-grader Kayleah Wilson's body was recovered this week from an irrigation ditch in an industrial area about a half-mile from her house. She had been missing since March.
Authorities say Kayleah's death was a homicide and they know how she died, but aren't releasing details.
Police say Montoya was arrested Wednesday, the day Kayleah's body was discovered. Montoya faces a felony charge of sexual assault on a child. Our sister station in Denver KUSA reports Montoya is Wilson's former boyfriend.
