UNDATED (WSAU) Today is the six-year anniversary of an unsolved murder in Marathon County. Ken Juedes was found shot in his bed by his wife on August 30, 2006. Police believe he was killed the night before by two shots to the torso. No one was ever arrested.

Police initially reported that Juedes' wife's shotgun was missing. Some time later they said the gun had been taken a year earlier and probably wasn't the murder weapon.

Sheriffs investigators also say they received an anonymous letter six months later that contained details only the killer would know. It was mailed from St. Paul, Minnesota.

Police are hoping someone will come forward with new information. You can leave an anonymous tip at the Crimestoppers hotline, 877-409-8777.
