William F. Muller, 45, was last seen on March 24, 1987, after finishing work in Philadelphia and getting into his black 1983 Plymouth Turismo for the drive to his home in Nockamixon Township near Doylestown, Pennsylvania. He never arrived. Family members found a pot of spaghetti left on the stove and his guns undisturbed in a cabinet, but William and his car were gone.

Two weeks before his disappearance William had filed a lawsuit against his younger brother, Frederick William Muller, over their deceased mother’s estate, a farmhouse on 17 acres. William reportedly believed Frederick was using the property for a narcotics operation. The lawsuit was dropped after William vanished. Years later investigators described Frederick as a suspect in the probable murder of William, and Frederick was arrested on drug charges in 2000 when methamphetamine manufacturing at the farmhouse was discovered. No charges were filed in William’s disappearance.

Seven years after he was last seen William was declared legally dead and his estate was distributed. Does anyone have information about William’s movements on March 24, 1987, or about that Plymouth Turismo?
