Getting on reality TV: Is it a gift from up above – or a pact with the devil?

From American Idol to Gordon Ramsay’s Kitchen Nightmares to Survivor, numerous shows have been touched by the horrific death of contestants who pursued fame in the no holds barred world of reality TV.

The bizarre death of an America's Got Talent contestant's wife is still the subject of an active police investigation, RadarOnline.com has exclusively learned.

In a letter to the family of Laura Finley, Captain Todd C. Chamberlain, commanding officer of the Central Community Police Station in Los Angeles, advised the woman's distraught father-in-law there was "a lot of work still being done on this incident."

Another Lieutenant, a veteran of the LAPD, has been assigned to the case, Captain Chamberlain wrote in his letter.

Joe Finley is determined to find out who killed his wife.

The day Finley auditioned for the talent show America’s Got Talent in the fall of 2010 his wife Laura went missing, and was found dead in the Los Angeles hotel where they were staying and where he tried out for a coveted spot on the reality show.

Despite an intensive investigation, police have not arrested anyone to date in connection with Laura’s murder.

In a new legal move, Finley’s high profile attorney Sean Macias has subpoenaed the show’s production company, asking for all video and photos of the day for all of the contestants, according to the documents obtained exclusively by RadarOnline.com.

A man, believed to be a security guard, was inside an America's Got Talent contestant's wife's hotel suite shortly before she supposedly plunged down a staircase to her death.

That's according to Laura Finley's devastated husband Joe, who has insisted, again, that his was brutally murdered in the hours before he audition for the hit NBC show.

Police have declared the death was not at all suspicious, although the cause of death has never been declared an accident, homicide or suicide.

An autopsy report has officially determined the cause of death of the wife of an America's Got Talent contestant as trauma.

In the post-mortem examination report obtained exclusively by RadarOnline.com, the Department of Coroner Los Angeles County spelled it out in one cold, hard conclusion: 48-year-old Laura Finley died of multiple blunt force injuries.

Her skull separated from the spinal column during a severe head injury, the documents which you can read here revealed.

Laura had a one inch laceration on the top of her head and a "diagonal gaping laceration measuring three-and-a-half inches" on her scalp.

Former America's Got Talent contestant Joe Finley is suing the swanky LA hotel where his wife was murdered last year because he claims a security breach let a homeless man sneak in resulting in her death, and RadarOnline.com has the legal papers.

The wrongful death lawsuit, which was filed on Wednesday with the Superior Court of California in Los Angeles, claims the Millenium Biltmore Hotel was negligent on the night his wife, Laura, was murdered because their lapse security policy allowed vagrants to wander in unattended.

LEGAL DOCUMENTS: Joe Finley Files Wrongful Death Suit Against Hotel

The luxury hotel was being remodeled on the night of October 22, 2010, when Joe and Laura Finley checked in before Joe’s reality show audition, and the legal complaint claims that staff didn't take adequate security measures to ensure that non-guests or transients couldn't enter the premises.

The America's Got Talent contestant whose wife was found dead in a Los Angeles hotel says she was brutally raped, strangled and robbed before her body was moved to the bottom of a staircase to appear like she fell.

Speaking exclusively to RadarOnline.com, a devastated Joe Finley said he was convinced Laura, 48, was murdered after being sexually assaulted at the Millennium Biltmore Hotel on October 23.

He said there's yet-to-be-released evidence that will prove his stunning claims, including DNA found under Laura's fingernails from when she scratched the killer during the rape.

"It's obvious that she was murdered," Joe told RadarOnline.com, breaking his six-week silence on the mysterious case.

"I believe she was raped, killed and her body was moved, (to the bottom of the staircase) and the scene was staged to make it look as though she'd fallen to her death."

The mother-of-three vanished while her rocker husband was waiting in line to audition for the hit NBC show.

Her body, clad in just her underwear, was found at about 8 a.m. and investigators initially believed she'd plunged eight stories to her death.

Joe, a singer/guitarist who went ahead with his audition in front of judges Piers Morgan, Sharon Osbourne and Howie Mandel, said he learned of his wife's death when police showed him a graphic photo.

"I believe she was strangled," he said. "As soon as I saw the photo, I said, 'Someone strangled my wife' because I could tell, from looking at her.

"I kissed her on the lips on the piece of paper and then they took it from me."

Joe also revealed Laura was found without three expensive diamond rings when she was discovered.

"She was wearing three expensive solitaire diamond rings all stacked on one finger and those rings were missing, I believe stolen, when she was found," said Joe.

"But I don't believe that was the motive, I believe the motive was rape and she was fighting to save her life. This was a rape that went too far."

In a case that has baffled Hollywood, Joe said he has been forced to launch his own investigation and has employed private investigators to find out how his wife of 26 years died, because "police are not telling us anything."

Cops believe the case is a tragic accident, but unconvinced, the musician has offered a $25,000 reward for information leading to the arrest of the perpetrator.

"It's impossible that she fell down the stairs or over a railing," Joe told RadarOnline.com.

"One, Laura would not be using the staircase if there was an elevator right there, and two, if you fall over a rail you're going to the bottom, not ending up on another floor.

"Thirdly, one thousand deaths a year are caused by falling down stairs and the highest percent of that are elderly people. You know what percentage that put this case in; you don't have to do the math to figure it out."

Joe - who described himself as a "broken man with a family that is suffering hour-by-hour" - also accused cops of destroying the crime scene at the historic downtown Los Angeles hotel, where he and Laura had been staying after celebrating his AGT try-out.

"The police were wasting precious time and destroying a crime scene by allowing loads of people access the hotel," he said.

"They should have closed the hotel down and disallowed anyone from leaving the hotel."

Instead, Joe added, even his own son was able to collect his mother's belongings from their room, while the hotel continued to operate as normal.

"My son and nephew walked out with clothes we were wearing the night before," Joe said.

"I pray every day that the investigators haven't botched this and they're just not saying anything because they have not come up with a solution as to what happened to Laura."

Joe, who was named a person of interest in the death, said cops interrogated him for nearly seven hours, all while he was handcuffed to a chair and wearing nothing but underwear.

"The police made me strip down because they were looking for scratches on my body, probably looking for marks that could have indicated there was some sort of struggle," Joe said.

"There wasn't any... God knows how many hours I was stripped down to my underwear, handcuffed to a f**king chair, in pain and screaming for help, to have the cuffs loosened.

"If I am a person of interest, I am ok with that given it is a general rule of thumb in investigations like these. However, all this time, the killer is still out there.

"I was even threatened by the police if I was seen on surveillance video that I could do 20-years-to-life and my response was:'f**k you'."

Joe said his offer of a polygraph was rejected.

He added, "I'm tired of it...it is not our style to remain silent. Laura and I fought for what we believe in. I just wish someone would look into this as I am spending my life savings on trying to figure out what happened to my wife."

Finley is being called a "person of interest" in the death, according to cops.

Sutterlin previously told RadarOnline.com Laura’s body was moved to the foot of the hotel’s stairs, in what she believes was a deliberate decision by the person who "murdered" her.

"Because of the way the stairway has been shown in photos in the media there was no way that the way her body was found with no visible trauma," Sutterlin said.

"The coroner said he's thinking supposedly they're ruling it an accident, according to the media, but there's no possible way to fall that kind of a distance and (not) have more trauma to your body.

"That's why the murder aspect is being considered by our family… somebody put her there... after someone, yes, [killed her.]"
