Born Robert Sylvester Kelly, the 58-year-old Grammy-winning R&B singer is serving sentences at a prison in Butner, North Carolina, for child sex crimes and racketeering.

Federal prosecutors in Chicago filed a motion strenuously objecting to Kelly’s request for release and disputing the “fantastic allegations” in the disgraced singer’s motion.

R. Kelly was convicted in two separate trials — one in New York, another in Chicago — of racketeering conspiracy and child pornography charges.

The Grammy-winning, multiplatinum-selling R&B songwriter was convicted in 2021 in Brooklyn federal court of multiple charges, including racketeering and sex trafficking.

In a petition filed last week and unsealed Monday, Kelly’s defense team asked the court to take another look at the case after a lower court rejected his appeal earlier this year.

The Seventh Circuit Court of Appeals on Friday rejected the R&B singer’s claim that the statute of limitations had passed and instead affirmed his convictions, stating that “(f)or years, Robert Sylvester Kelly abused underage girls.”

Attorney Jennifer Bonjean, seeking to reverse his 2021 convictions or to win him a new trial, tried to persuade three judges on the 2nd U.S. Circuit Court of Appeals in Manhattan that prosecutors improperly used a racketeering statute written to shut down organized crime to go after the singer.

The Hennepin County Attorney’s Office said in a statement Tuesday that it believes her and that Kelly would likely be convicted if tried, but prosecuting him on charges that had been dormant since being filed in 2019 wouldn’t make a difference now that Kelly’s federal convictions could keep him in prison for the rest of his life.

Robert Sylvester Kelly was transferred from the Metropolitan Correctional Center Chicago to the federal correctional institution in Butner, North Carolina, on April 19, Federal Bureau of Prisons spokesperson Benjamin O’Cone said Monday via email.

Kelly’s attorney Jennifer Bonjean on Thursday filed her notice with the 7th Circuit Court of Appeals. That move is not a surprise, as Bonjean last month noted her intent to appeal Kelly’s convictions on three child pornography and three child enticement charges.

Federal prosecutors asked U.S. District Judge Harry Leinenweber to sentence Kelly to 25 years in prison to account for the “indescribable harm” he caused his victims, including his then-underaged goddaughter “Jane.”

“Plain and simple, Kelly does not comprehend that what he did was wrong," federal prosecutors said in a sentencing memo this week.

A federal judge has denied R. Kelly’s request for a new trial, just a week before he is set to be sentenced on child pornography charges following his conviction in Chicago last year.

R. Kelly has already been convicted in other jurisdictions and sentenced to decades in prison, with more time likely to be added during a sentencing hearing next month.

Cook County State’s Attorney Kim Foxx on Monday announced her office will be dropping its case against Kelly — nearly four years after he was arrested and charged with multiple counts of sexual assault and abuse.
