The plaintiff in the lawsuit filed Monday in Philadelphia Common Pleas Court does not want to be identified by name but by the initials S.D., Eisenberg said. S.D. was a member of Boy Scout Troop 100 in Plains Township, near Wilkes-Barre. Starting around 1975, when he was age 12 or 13, S.D. was sexually abused for about five years by an assistant scoutmaster in his troop, the suit says.
