(BAD AXE) -- The son of the late sex research pioneer Dr. William H. Masters faces a court hearing on a charge that he exposed himself to a sheriff's deputy and another woman the Pinnebog River. William H. Masters III is scheduled to be arraigned in Huron County Circuit Court on Monday. He's charged with aggravated indecent exposure, punishable by up to two years in jail. Authorities say a completely nude Masters yelled for the women's attention on September 1, then made obscene gestures. Defense lawyer Dennis Johnston says he's going to let the "criminal justice process play itself out." Masters is a 60-year-old resident of Southhampton, New York. He pleaded guilty last week to conducting a lewd act in Central Park back in May. Masters avoided jail time in that case, but if he gets arrested again he'll face up to 90 days in jail.
