MAYVILLE, N.Y. — A jury in western New York on Friday found a New Jersey man guilty of attempted murder in the stabbing of author Salman Rushdie, which left him partially blind. The conviction of the man, Hadi Matar, 27, followed harrowing testimony from Rushdie, 77, who said he had been struck by his attacker’s dark, ferocious eyes. He told the jury that at first he felt he was being punched, but then he realized he had “a very large quantity of blood pouring out” onto his clothes.
