A coronary artery clot was given as the cause of death. He died in suite No. 3327 at the New Yorker Hotel in New York. Tesla's corpse was found by a maid who entered the scientist's room, ignoring a "do not disturb" sign on the door. Tesla's nephew Sava Kosanovic entered the room the day after discovering the corpse. He found that his uncle's scientific notes and black notebook with several hundred pages, including some signed "Government Affairs," had disappeared. Soon all of his items were confiscated by the Alien Property Custodian, even though he was a full-fledged U.S. citizen.
