It has been a mystery for 7 and a half years. Who killed a popular teacher in Kiowa, Colorado and left his body in a field?

The Elbert County Sheriff’s Office announced Tuesday afternoon that they have arrested 34-year-old Daniel Pesch for his alleged role in the death of Randy Wilson, whose body was spotted by someone driving by a remote field in Elbert County in June 2010.

Wilson’s hands were bound. There was a bag over his head and a belt around his neck.

Citing a court order, the Elbert County Sheriff’s Office could not release much information about the case on Tuesday, other than that Pesch faces charges for first-degree murder, resisting arrest, obstructing a police officer and attempted escape.

It’s unclear if he knew Wilson, or what the motive may have been for the murder.

Brett Robinson was a superintendent for the school district where Wilson worked before his murder. He says he was called by the sheriff’s office to identify his friend’s body.

“He was a great teacher, a great father, and he had a dry sense of humor that was really fun to be around,” Robinson said.

“He did not deserve to be out in that field,” he added. “Everything about it was wrong.”
