Dana Martin: Who is the man allegedly behind the Justin Bieber murder plot?

Justin Bieber may be adored by millions around the world, but this week, we learned there are some who hold incredibly sinister thoughts about him -- specifically, Dana Martin, the man who allegedly attempted to orchestrate the murder of the 18-year-old pop star.

Police in Albuquerque, N.M., confirmed a complicated murder plot on Wednesday allegedly masterminded by Martin, who is currently serving two life sentences in prison for raping and killing a girl in Vermont. Police say Martin, 45, hired his former prison acquaintance Mark Staake, 41, and Staake's nephew Tanner Ruane, 23, to murder four people, with the main target being Bieber. Martin's reported goal was to attack the Stratford, Ont., singer at his sold-out performance at Madison Square Garden in November.

This is not the first intricate scheme Martin has been connected to since he was put behind bars and, disturbingly, it's also not the first time it has involved a teenager.

In 2009, while serving time at Cross City Correctional Institution in Dixie County, Florida, Martin was charged with sending threatening letters to a 16-year-old Florida girl, the sister of one of Martin's fellow inmates. Martin got her personal information from her brother -- including her address, name, age, and school -- and wrote to her under the name of his cellmate, Macon Higgs. The letters were violent in tone, insinuating that Higgs would soon escape from prison to attack the girl and that she was under surveillance.

Martin meant to frame Higgs so that he would be replaced in the cell with another inmate willing to help with yet another elaborate plan Martin had hatched -- this time, to escape the penitentiary. But authorities discovered the letters' true author and his intention to flee and gave Martin 10 more years in prison.

Before his murder conviction in 2009, Martin also reportedly served time for sending threatening letters to a judge. When it comes to Bieber, Martin is described as having an "obsession" with the "Believe" singer (including sporting a tattoo of Bieber on his leg), and he allegedly hatched the murder plot out of anger that his many letters to the star went unanswered.

It's probably safe to say that Bieber won't be making contact with Martin now that the news is out. Hopefully it didn't distract him during his performance at Power 96.1′s 2012 Jingle Ball in Atlanta, Georgia, on Wednesday night, where he surprised fans with a guest appearance by Ludacris on "Baby."

"that was fun ATL. always good to be back here. thank u to big bro @Ludacris for coming out on stage tonight. it got LOUD! haha. #MUCHLOVE," Bieber tweeted after the show.

In response to the murder plot, Scooter Braun, Bieber's manager, told Us Weekly, "We take every precaution to protect and insure the safety of Justin and his fans."

It's a good thing for Bieber -- and his millions of fans worldwide -- that Braun and the Albuquerque police have his back.
