It’s been more than a year since 33-year-old Martha Nolan was found dead on a wealthy Montauk entrepreneur’s yacht last August and police have yet to release her cause of death or any updates on the investigation. So now, Nolan’s family is asking the public for information, setting up a website and tip line just days after filing a $50 million lawsuit against Christopher Durnan, the man who was alone with Nolan when she died. Even though police say she showed no signs of violence, Nolan’s family says their independent investigation showed there was blood in her mouth, chest and back of her head when EMTs showed up more than an hour after she reportedly “went limp” on Durnan’s yacht.
