SHAWANO, Wis. (AP) — Authorities say human remains have been found on a northwest Missouri farm that has been the focus of a search for two missing Wisconsin brothers. Clinton County Sheriff Larry Fish announced Wednesday the remains were found on a farm near Braymer. He says the remains have not been officially identified. No cause of death has been determined. Authorities have been searching a farm near Braymer for 35-year-old Nicholas Diemel and his 24-year-old brother, Justin Diemel, who have been missing since July 21. The farm was operated by Garland Joseph Nelson, who authorities say moved a rental vehicle the brothers were using during a trip to Missouri for the livestock business they operated in Bonduel, Wisconsin. Court documents indicate the brothers visited the farm and Nelson was later seen driving their truck away. It was later found abandoned in a commuter parking lot.
