Joseph Muelbl, 31, of Milwaukee was last heard from on October 16, 2008. That day he made several calls to loved ones in which he sounded confused and disoriented; his final call was to his mother, during which he said he loved her and apologized if he had hurt anyone. The line went dead soon afterward and he has not been heard from since.

Joseph’s Ford Explorer SUV was found the next day abandoned in the parking lot of a Menard’s store in Germantown, Wisconsin. He had a steady job at Kangaroo Brands Inc. and was described as a devoted father. Rumors mentioned possible drug problems in the months before his disappearance, but he left no explanation for why he vanished. Investigators list his case as missing under suspicious circumstances and continue to seek leads.

If anyone knew Joseph, saw his SUV, or has information about his movements on or before October 16, 2008, please come forward.
