Police respond to a 911 call in the high society area of the Hamptons at the Montauk Yacht Club shortly after midnight.

Martha Nolan-O'Slattarra, a fashion designer from Ireland, is found unresponsive on a boat named "Ripple." The yacht is reportedly owned by insurance mogul Christopher Durnan, 60, who was present at the scene and allegedly ran down the dock screaming for help.

The wealthy yacht owner was once accused of fighting and biting a former New York firefighter during a tribute concert, commemorating 20 years after the 9/11 terror attacks.

CPR is attempted by a good Samaritan, but first responders pronounce Martha dead at the scene. Initial autopsy results showed no signs of violence. As rumors swirl of drug overdose, Martha's family strongly denies those claims and rumors of brain cancer by hiring attorney Arthur Aidala to ensure a thorough investigation is performed.

The official cause of death is inconclusive, pending toxicology reports.
