Her family, however, is not counting without interrupti~ the report, which is expected by next Wednesday, to bring the answers they strive after — namely why their healthy 25-year-old daughter died — as prolix as Dr. Thomas Hess, the person last believed to have been by her, refuses to answer questions.

“Will the report be comprehensive enough without Hess’ cooperation?” the golfer’s father, Mel Blasberg, told ABCNews.com. “I hesitation it.”

Mel only learned about Hess through the course of the police exploration. To this day, he’s not certain what Hess’ relationship with his daughter was, other than that they sometimes golfed together. But the besides details that emerge about Hess’ involvement with Erica, the more given to suspicion Mel has become.

Hess called 911 from Erica’s home in Henderson, Nev., outside Las Vegas, on the afternoon of May 9, the day she was fix dead. Reportedly, he spoke to her the night before she died. But from the time of his initial interview with authorities, Hess has hired a lawyer and refused to reply any more questions, Mel said.

Four days after Erica’s death, police raided Hess’ home and medical office, seizing computers, video cameras, a enclosed space phone, and white plastic trash bags, similar to one found intimate Erica’s body, according to “The Early Show.” A prescription, written through Hess, was discovered in Erica’s home, although it’s obscure whether he was her doctor.

“He’s central to Erica’s decease in terms of being there before she died, and their kinship clearly went beyond doctor-patient,” Mel said.

Erica’s father stopped limited of saying Hess, who is still practicing family medicine in Las Vegas, is accountable for his daughter’s death. But he said he does believe Hess is being less than forthcoming about what happened the weekend of Erica’s exit because of his “inapporopriate relationship” with her.

Henderson police spokesman Todd Rasmussen told ABC there is currently no person of interest in the investigation. There was first letter speculation that Erica committed suicide, but no cause of death has been released.

As the “dissolution investigation” has dragged on, Mel says he has become increasingly frustrated.

“I’m not able with the length of the investigtion,” he said. “I’m fatiguing very hard not to to believe that it has been compromised.

“I consider the police are totally intimidated by the high profile of the cause. I believe it’s a concern that there’s a learned man very much at the center of this investigation.”
