Updated 3:50 p.m. -- Two new laws bring Colorado into line with U.S. Supreme Court rulings that bar youth offenders from getting mandatory life sentences without parole.

The laws affect 48 Colorado inmates serving life without parole. The inmates were convicted of first-degree murder and other crimes committed as youths between 1990 and 2006.

Those 48 can seek - but are not guaranteed - new sentences under one bill signed into law Friday by Gov. John Hickenlooper.

A companion law allows youth offenders who've served at least 20 years to apply for an early parole transition program. Anyone who completes it still must seek clemency from the governor.

Colorado ended no-parole sentencing for youth offenders in 2006.
