The Drowning of Natalie Wood and Three Updates

In November of 1981 actress Natalie Wood ventured out into the ocean off of the California Coast aboard the Splendour, her husband's yacht, accompanied by her husband, her current movie co-star, and the captain of the yacht.  Sometime during the night, Natalie ended up overboard.  Her body was found in the morning, and over the last 40 years her death has been debated as accidental or possibly something more sinister.

There are also three case updates to Episode 8, Episode 10, and Episode 54.
