Natalie Wood’s death was initially determined to be an accident. Then, in 2011, the investigation was reopened, because of reported new recollections of the night Natalie Wood died from the boat’s former captain, Dennis Davern. “The police actually went to Hawaii where the “Splendour” is now, and they took Dennis and they conducted noise tests to prove what he was telling them was true, says Dylan Howard, Investigative journalist and host of the podcast Fatal Voyage: The Mysterious Death of Natalie Wood. He says what Dennis claims to have heard that night “is chilling.”
