Mass Killer Pins Target On Bill Cosby's Back In Prison

After four months of pampering, convicted sex fiend Bill Cosby has finally been moved into a Pennsylvania prison's general population, where he's being targeted by a bloodthirsty mass murderer, sources revealed to RadarOnline.com.

SCI Phoenix inmate George Banks, 76, a spree killer convicted for the brutal murder of five of his children, two babies, five women and a man, has it in for the disgraced TV dad, a source warned.

For some reason, Banks insisted the once-popular sitcom The Cosby Show "destroyed his family," according to the source.

Now that Cosby's in the general population with 2,000 other prisoners after being housed in a special unit in the immediate aftermath of his September sentencing, the 81-year-old comic could easily be attacked as he showers, exercises, eats or sleeps, insiders noted.

Cosby is so fearful, he's had his people "deposit money into other inmates'" prison accounts "in exchange for protection from the gangsters in Banks' circle," the source claimed.

However, prison officials insist Cosby is safe from Banks, who is housed in the capital case unit and banned from any other units at the penitentiary.

But that won't stop Banks from "sending his hit men after Cosby," said law enforcement expert Alan Davis, who retired as a captain after decades with the Chester, Penn., police force.

"Prisons are their own little worlds with politics, economy, favors and ­alliances, so I wouldn't rule out anything as being impossible in there," said Davis.
