August 20, 1940: Author Cox was arrested and charged with the murder of Deputy Sheriff Dean Pray. Cox had been actively working in association with Watchtower for 33 years prior, and had been assigned at the time by Watchtower to the Portland, Maine congregation of Jehovah’s Witnesses. Cox carried credentials issued by Watchtower’s President, J. F. Rutherford. A few weeks prior to the killing of officer Pray, Cox had purchased a revolver to carry in the book-bag he carried in his public ministry. This is the firearm Cox used in the killing of officer Pray. Cox claimed self-defense. Attorney Hayden Covington was assigned by Watchtower as defense counsel.[6] Cox was convicted of murder and appeal was denied.
