A former facility administrator for the Eastern Pre-Release Unit in Church Hill is charged with three counts of second-degree assault and three counts of fourth-degree sex offense in Queen Anne’s County District Court. William “Buster” Theodore Blackiston Jr., 63, of 729 Round Top Road, Chestertown, is charged with assaulting two women in three separate incidents in May and September 2010. One woman allegedly was assaulted between May 10 and 14, 2010, and again between May 17 and 21, 2010; the other woman on or about September 30. Queen Anne’s County State’s Attorney Lance Richardson said the charges stem from alleged assaults of workers at the facility. An employee of the pre-release unit said that Blackiston retired from his position there in December.
