 William Monahan later testified that after the struggle, he saw Mr. Baez, handcuffed, stand up and walk briefly, with assistance from Officer Francis Livoti, contradicting claims by Baez's family that he was already limp when cuffed.Livoti was the subject of several civilian complaints for excessive force, though none had been substantiated by the Civilian Complaint Review Board.In his defense, Livoti denied that he had used a choke hold, asserting that any choking was unintentional and that he had not caused Baez's injuries or death.
