A judge in central Illinois has handed down a 54-year prison sentence for a 44-year-old Champaign man convicted of molesting two girls.

Judge Heidi Ladd sentenced Manuel Martinez for his conviction on charges of predatory criminal sexual assault of a child, criminal sexual assault and aggravated criminal sexual abuse.

Authorities say Martinez was charged after the August 2010 attacks on an 11-year-old and a 13-year-old in the apartment he shared with one girl's mother.

Assistant State's Attorney Adam Dill had sought the maximum 75-year sentence.

Martinez told the judge he's innocent and was wrongly accused.
