MODERATE
This bill amendment changes the age eligibility criteria for a new sentencing provision from being 18-20 years old to specifically being 18, 19, or 20 years old at the time of the offense. It also reduces the minimum prison term from 80 years maximum/35 years minimum to 60 years maximum/25 years minimum if life without parole is not imposed.
Scope change
The bill's scope was narrowed slightly by clarifying the specific ages (18, 19, or 20) rather than the broader range (more than 18 but less than 21), and the sentencing thresholds were lowered.
ELIGIBILITY
Changed age eligibility from 'more than 18 but less than 21' to specifically '18, 19, or 20 years of age' at the time of the offense.
REQUIREMENT
Reduced mandatory prison sentence terms from 80 years maximum/35 years minimum to 60 years maximum/25 years minimum when life without parole is not chosen.
