The popular singer (Photo) is threatened with death

We have often heard cases when a fan “is tested” behind a favorite singer or actor, thus becoming a dangerous person.

One such case has happened to Taylor Swift, who for several months has received threatening messages from a fan who threatened with life.

But it wasn't enough to have Andrew Hoover, 40-year-old who was persecuting Taylor, since he threatened to kill her family.

Letters filled with threats to the singer have led the respective Los Angeles authorities to launch investigations into Andrew Hoover to see if he has psychological problems.

Everything happened after the 40-year-old in 2016 failed to enter an Taylor concert.
