TMZ has learned that there were six people, including Anna, staying with her in her two-bedroom suite at the Seminole Hard Rock Hotel and Casino in Florida.
The private nurse, who discovered Anna unresponsive, is the wife of Anna's bodyguard. The bodyguard, who is also a paramedic, administered CPR to Anna until an ambulance arrived. Anna's companion, Howard K. Stern, was staying in the room as well.
The identities of two other individuals are, at this time, still unknown.
