A former Baltimore County priest is facing child sex abuse charges. Police say detectives with the Crimes Against Children Unit began investigating William “Father Bill” Mannion in October 2023. The alleged abuse occurred from about 1991 through 1994 in the 600-block of St. Agnes Lane in Catonsville. Mannion was arrested Monday and is charged with second-degree child abuse and multiple sex offenses. Detectives believe there may be more victims of Mannion’s abuse and urge them to come forward.
