Justin Bieber Murder Plot Tapes:

A convicted murderer's terrifying phone call to a hit man -- in which he describes a plot to murder and castrate Justin Bieber and his bodyguard -- has been released.

The phone call -- obtained by KOAT 7 News in Albuquerque, NM -- was placed from a Las Cruces prison last November by Dana Martin, who's currently serving two life sentences for raping and killing a 15-year-old girl.




According to police, "pit bulls" was the code word for Bieber and his bodyguard.
In the call, Ruane mentions the "hedge clippers" he was planning to use to carry out the deed.
Martin also describes how to perform the murders using his signature paisley tie -- "Tie it really really tight. Knot it in the front once, really tight, put it in a knot. That cuts off the oxygen, and then tie it in the back again, really tight. That seals the deal."
As we reported, the murders were supposed to go down in New York City soon after this telephone call took place ... while Bieber was in town performing at MSG. Ruane and Staake were subsequently intercepted by police before anything happened
