A convicted killer locked up in New Mexico plotted to have Justin Bieber murdered and castrated ... but for some mysterious reason, he threw a wrench into his own plans -- this according to a local news report in New Mexico.
According to KRQE News, convicted murderer Dana Martin -- currently serving two life sentences for raping and killing a 15-year-old girl in Vermont in 2000 -- recruited a fellow inmate at Las Cruces prison named Mark Staake to carry out the murder once Staake was released.
It's unclear when the plot was originally hatched, but Staake and his nephew Tanner Ruane -- whom Staake had later recruited to help -- reportedly planned to execute the murder plan in NYC last month, where Bieber was performing at MSG.
Martin reportedly told police the plan was to kidnap Bieber and his bodyguard and strangle them with paisley ties, Martin's calling card. Ruane was then going to castrate them.
According to KRQE, Martin is obsessed with Bieber and even has a tattoo of Bieber on his leg.
But for some reason Martin blew the whistle on his accomplices -- and Staake was arrested in Vermont on outstanding warrants before carrying out the deed.
Ruane made it to NY with a stash of tools -- including pruning shears -- but according to the report police intercepted him before anything happened, and placed him under arrest.
