The FBI on Monday released a cache of 128 pages of letters and other documents related to the singer, spanning the years 1988-92.

Included is a long series of handwritten notes from a devoted fan, who proclaimed his love for Houston and detailed his desperation to meet her. He urged the singer to "keep smiling" at the end of his letters and pleaded for a meeting. His requests grew more desperate as he attended concerts, attempted to give her flowers and wrote more and more letters, which were ignored.

"I might hurt someone with some crazy idea and not realize how stupid an idea it was until after it was done," he wrote, his frustration mounting. In total, he wrote more than 70 letters to the "I Will Always Love You" singer.

Another series of documents details a blackmail plot against Houston, conducted by a woman who alleged that she had sensitive and embarrassing information about the singer's relationships and personal life.

The woman's demands climbed from $100,000 to $250,000. Houston, who died in February 2012, admitted having discussed personal matters with the woman, and her father ultimately sent the woman a payment to buy her silence.
