The Whitney Houston FBI files have been released due to Freedom of Information Act requests as of March 4, 2013.

The document numbers 128 pages and includes several fan letters and FBI paperwork about an extortion case involving the late Whitney Houston, according to USA Today.

The case was eventually closed without anyone being prosecuted, but the FBI file documents suggest that Whitney Houston paid off the person demanding 'hush money'.

The 1992 letter marked "extortion" by the FBI was sent to Houston's New Jersey office of Nippy Inc. The letter, written by a woman, demanded that unless Houston paid her $100,000, "certain details of her 'private life' would be revealed. A later letter increased the amount to $250,000 and claims that the woman knows details of Houston's romantic relationships.

The FBI interviewed Houston, who told agents she considered the woman 'a friend' and 'did discuss personal things' with her.

The documents suggest that Houston's father then sent the woman a confidentiality agreement with a sum of money that the FBI documents kept blacked out.

The case was closed soon after.

The fan mail mostly professes the overwhelming adoration of the type found in Houston's movie, Bodyguard, which can sometimes lead to stalking.

One letter provoked the FBI to investigate the writer further, since its writer "might hurt someone with some crazy idea and not realize how stupid an idea it was until after it was done."

The fan wrote, "Miss Whitney, you are just so pretty and so beautiful. I just cannot stop thinking about you. Many times when I think about you I will start to shake...I really and truly am in love with you."

In another letter, the writer states, "Over the past 17 months, I have sent...66 letters to Miss Whitney...I have been to 9 of Miss Whitney's concerts and I have tried to give her flowers twice at the concerts. ...When I first fell in love with Miss Whitney Houston I tried to ignore what I felt towards her. After 5 months I had to do something so I started writing letters. I have tried to stop writing the letters and to give up twice but after I few weeks I had to start writing again."

The writer continues to explain that Houston's lack of response was frustrating. He wrote, "I have gotten mad at her a few times...it scares me that I might come up with some crazy or stupid or really dumb idea that might be as bad or even worse than that...I might hurt someone with some crazy idea."

Later on, he wrote, "Miss Whitney, why can't you respond to my 70 plus letters?...You probably think I'm crazy. Well, (maybe) I am. I just can't give up. I have to keep trying. I really am in love with you."

The FBI marked one of his letters as a possible attempt at extortion because the writer included a line about making his love for Houston publicly known on print and Television.

But, when agents interviewed the writer at his small apartment, they determined, "He believed this 'crazy idea' would have hurt Houston's reputation so he did not follow through on it."

Whitney Houston passed away on February 11, 2012 from drowning in her bathtub after ingesting various drugs.

The late award-winning singer is still considered one of the greatest music artists of her generation.
