Patricia WelchBEDFORD, Va. (AP) _ A Maryland woman faces a perjury charge in Virginia stemming from an investigation into the disappearance of two sisters in 1975. Media outlets report that a Bedford County grand jury indicted 65-year-old Patricia Jean Welch of Hyattsville, Maryland, on Tuesday. Welch is accused of lying to a grand jury investigating the case of 10-year-old Katherine Lyon and 12-year-old Shelia Lyon. The girls disappeared after walking to a shopping mall in Wheaton, Maryland in March 1975. Authorities have named Patricia Welch’s husband, Richard Allen Welch, and his nephew, Lloyd Welch, as “persons of interest” in the case. Neither man has been charged. Welch’s trial is scheduled to begin Oct. 13.
