LAS CRUCES, N.M. — Justin Bieber played for a sold out house just a few weeks ago at Madison Square Garden in New York City.
That's where investigators say Mark Staake and his nephew Tanner Ruane planned to take down the teen sensation.
Turns out their Bieber Fever started long ago, at the state prison near Las cruces.
That's where Staake met Dana Martin, a convicted killer serving two life sentences for raping and killing a 15-year-old girl in Vermont, in 2000.
Martin recruited Staake who in turn recruited his nephew to carry out four murders after Staake got out of prison.
Police say Martin asked the two to first go to Vermont and take out two former acquaintances.
He gave strict orders to strangle the victims with a paisley tie.
Tanner Ruane was in charge of castrating the victims.
Martin told cops there was a bigger plot, the murder and castration of Bieber and his bodyguard.
Turns out Martin is obsessed with Bieber and even got a tattoo of the superstar on his leg.
Staake was arrested in Vermont on outstanding warrants before carrying out any of the killings.
NYC police arrested Ruane, who had murder tools and pruning shears with him.
