Cash wasn't the only thing ruling everything around the Wu-Tang Clan in the '90s. The FBI was lurking around the hip-hop group in 1999, to determine if Raekwon and RZA were connected to two murders in Staten Island.

Brian Humphreys, a former gang member, told the New York Police Department in 1999 that the murders of Jerome "Boo Boo" Estella and Corey "Shank Bank" Brooker were ordered hits from the two Staten Island rappers -- apparently the deceased robbed two family members of Raekwon and RZA.

However, in October of 2014, a federal jury found Anthony Christian guilty of the murder of Estella. Anthony, along with his brother, Harvey Christian, were also found guilty of running a 20-year drug-dealing business. The murder of Brooker, who was shot three days after Estella, remains unsolved.

The contract hit went for $30,000, according to Humphreys, whose testimony is relayed in the court filing.

"A couple of weeks before the Boo Boo shooting, Uncles (the street name of drug supplier-turned-informant Paul Ford) told Humphreys about a Blood named Boo Boo who just came home from jail. He stated that Boo Boo had robbed RZA's little brother and had also gotten into something with the Christian brothers," read the court filing. "Uncles was talking about Boo Boo and said that he had just come home and robbed RZA's brother and that they would likely come after him for that. Humphreys believes Uncles was referring to members of Wu-Tang."

Now, Anthony Christian's lawyer, Michael Gold, is seeking all of the police files -- possibly in hopes for a re-trial.

"These reports seem to suggest someone else was liable for those murders. I'm not suggesting that Wu-Tang committed these crimes. The FBI did," Gold told the Staten Island Advance. "What I'm trying to ascertain is their stated belief in an official file that Wu-Tang ordered this homicide."

According to the news site, representatives of Wu-Tang have not responded to their e-mail seeking comment on the newfound information.
