Sordid details have surfaced in audio tapes of phone conversations in a murder plot against teen pop sensation Justin Bieber that made headlines back in December, E! Online reports.

“Police told ABC News’ Albuquerque affiliate KOAT that inmate Dana Martin, who is doing time at the Southern New Mexico Correctional Facility for the murder and rape of a 15-year-old girl, was the mastermind behind the plot,” the story reports. “According to police, Martin directed a former jailhouse friend in Vermont, Mark Staake, and Staake’s nephew, Tanner Ruane, to carry out the kidnapping and murder, and asked Ruane in a taped conversation, ‘Did he go over the Bieber thing with you?’"

Ruane reportedly replied: "Nah. The way I like to work dude, I like to know as little as possible. He’s gonna use one of the things you gave him, and then he’s gonna take care of it."

Ruane adds: "We went and bought the hedge clippers. You’re gonna give me 5 large ($5,000) for each one I get."

The report notes: “Police said that Ruane was instructed to castrate Bieber and his bodyguard with the clippers, and then suffocate them with a scarf.”

Martin is reportedly heard saying: "Tie it really tight, and that cuts off all the oxygen, and then tie it in the back again, really tight. That seals the deal."

“Luckily, before any of this could take place, Staake and Ruane were arrested by border patrol agents after making a wrong turn in to Canada,” the piece reports. “They, along with Martin, now face two counts each of conspiracy to commit murder and two counts each of conspiracy to commit aggravated battery.”
