What's the deal with Diane Wolozin, Heath Ledger's masseuse?

No one ever really talks about Diane, and the fact that she and his housekeeper, Teresa, were the first people to enter the apartment where Heath's body was found. They all just go straight to Mary Kate Olsen, who was in his emergency contacts and asked for immunity after the fact. But if you try to look for Diane Wolozin, nothing ever comes up. I don't know why but I just get the feeling that there was foul play involved with Heath's death, and I've felt that way for 12 years. I just can't shake it. Anyone else?

"At about 3:00 pm (EST), on 22 January 2008, Ledger was found unconscious in his bed by his housekeeper, Teresa Solomon, and his masseuse, Diana Wolozin, in his loft at 421 Broome Street in the SoHo neighborhood of Manhattan.

According to the police, Wolozin, who had arrived early for a 3:00 pm appointment with Ledger, called Ledger's friend Mary-Kate Olsen for help. Olsen, who was in California, directed a New York City private security guard to go to the scene. At 3:26 pm, "less than 15 minutes after she first saw him in bed and only a few moments after the first call to Ms. Olsen", Wolozin telephoned 9-1-1 "to say that Mr. Ledger was not breathing". At the urging of the 9-1-1 operator, Wolozin administered CPR, which was unsuccessful in reviving him.

Paramedics and emergency medical technicians arrived seven minutes later, at 3:33 pm ("at almost exactly the same moment as a private security guard summoned by Ms. Olsen") but were also unable to revive him. At 3:36 pm, Ledger was pronounced dead, and his body was removed from the apartment."
