PHILADELPHIA (CBS) — A 23-year-old Philadelphia man has been sentenced to 6-12 years in prison for a vicious and sadistic vigilante-justice attack — in retaliation for a crime that did not happen.

Authorities say a woman set up the victim with a false rape claim.

The beating victim testified that Renada Williams, 31, invited him over for sex.  Later, authorities say, 23-year-old Shown Aiken and his teenaged brother arrived, prompted by a call from Williams claiming she had been sexually assaulted.

“They went over to her house, kicked in the door, found the victim completely vulnerable and naked in the middle of the bedroom,” notes prosecutor Joseph McGlynn.  “They began beating him with an extenstion cord, with a two-by-four, and ultimately they sodimized him with a broomstick after they taunted him and told him he was going to feel what it was like to be raped.”

The victim says he suffered a collapsed lung, broken ribs, and other injuries, and was hospitalized for a week.

The motive for the setup is unclear, although some items were stolen from the victim.

The woman pleaded guilty earlier and was sentenced to up to 23 months in prison. The teen is being handled in the juvenile system.
