Sinn Féin leader Gerry Adams has been arrested in connection with the 1972 murder and kidnapping of Jean McConville. Prior to his arrest Wednesday, Adams had declared he was “innocent of any part” in the murder of McConville, a 37-year-old widowed mother of 10 who was wrongly accused of being an IRA informer. Her body was found in 2003, and there have recently been multiple arrests in connection with the murder. Ivor Bell, a leader in the Provisional IRA in the 1970s, was arrested last month for his connection with the murder after a candid interview he gave to Boston College researchers. The interview was only supposed to be made available after his death, but some content was handed to authorities.
