Jackson Death Threat -- All Over a Woman

The person who threatened to kill Michael Jackson unless he got money also threatened to slaughter people at a Michael Jackson concert, according to documents just released by the FBI .. and it all appears to be a scheme to get a woman to notice him.

The person who wrote the threatening letters says, "I'll commit mass murder at a Michael Jackson concert if necessary, in an attempt to murder Michael, then you will have to deal with my situation in the public eye."

It appears from the letters the writer wants mobster John Gotti to fork over money and if he doesn't ... the writer threatens to kill Michael.

The person who wrote the letters appears to be obsessed with a woman and is making these threats to get her attention. Some of the letters were written to newspapers. He says, "I'm 33 years old and never had a real relationship in my life. I can't even slow dance."

The man was arrested on May 22, 1992 outside the White House. He was released on June 4, 1992, and one day later made threats to kill Michael Jackson.
