(HURON COUNTY) -- The 60-year-old son of sex research pioneer Dr. William H. Masters has admitted to committing a lewd act in New York's Central Park. William H. Masters III pleaded guilty Monday to misdemeanor public lewdness. He was arrested in May after a New York police officer reported the act. Defense lawyer Irwin Rochman says his client has been in counseling. Masters avoids jail time. But if the Southampton resident gets arrested again he'll face up to 90 days in jail. Masters also is charged with exposing himself to a Huron County Sheriff's deputy and another woman on the Pinnebog River in September. That case is pending.
