Topeka ? The Kansas Supreme Court on Friday set aside the 25-year sentence of a man convicted of multiple sex crimes.

The high court upheld the 2007 convictions of Gerald Gonzales on the crimes, punished under the state’s 2006 “Jessica’s Law,” which imposed stricter sentences for seven types of sex crimes.

But justices ruled that Sedgwick County prosecutors failed to prove that Gonzales was at least 18 years old at the time. Gonzales is 30 years old. The case was remanded for sentencing.

The crimes took place between 2004 and 2006. He was convicted of one count of aggravated indecent liberties with a child by engaging in sexual intercourse; one count of aggravated indecent liberties of a child by lewdly fondly or touching a child under age 14; one count of rape of a child under age 14; and one count of violating a protective order by contacting the victims’ mother the night before his preliminary hearing.

According to court records, Gonzales committed the crimes against two daughters of a woman with whom he was romantically involved. One of the girls suffered from cerebral palsy.

Jessica’s Law in Kansas calls for a minimum 25-year sentence for adults convicted of any of seven violent sex crimes against anyone under 14. The case was among a handful of rulings issued Friday by the high court, including a high-profile murder case in southeast Kansas.

In that case, the court upheld the murder conviction of a Pittsburg man found guilty of a 2006 shooting.

Albert E. Richmond was convicted and sentenced to prison for 50 years without eligibility for parole in the shooting death of Tyrone Owens. Owens was shot multiple times after selling marijuana to another occupant of a car in which Richmond was riding. Richmond was arrested in Florida 10 days after the shooting.
