In his latest trial, Kelly was found guilty by a jury on six out of 13 counts, prosecutors said.
In Chicago, a conviction of just one count of child pornography carries a mandatory minimum sentence of 10 years, Reuters reported.
Kelly is among the most prominent people convicted of sexual misbehavior during the #MeToo movement against sexual harassment and abuse in recent years.
During the five-week trial, several women took the stand and told jurors that Kelly sexually abused them when they were minors. The jury also saw a video of Kelly molesting his goddaughter, who testified that the abuse began in the 1990s when she was a teenager.
Kelly and both his co-defendants, Milton “June” Brown and Derrel McDavid, were acquitted on charges they conspired to receive child pornography. Kelly and McDavid were also acquitted on charges they conspired to obstruct justice in an earlier case.
The men were accused of trying to bribe and threaten witnesses in the 2008 Illinois case in which Kelly was found not guilty on 14 counts of child pornography.
In June, Kelly was sentenced to 30 years in prison on his conviction in a New York federal court on racketeering and prostitution charges. That trial amplified accusations that had dogged the singer of the Grammy-winning hit “I Believe I Can Fly” for two decades. read more
