I just checked another source and there are states that a life sentence can even be less than 10 years.
The following link details a state by state comparison showing vast differences of what a life sentence means.
“A capital offender in Florida is assigned a sentence of life with the possibility of parole after 25 years. However, Florida also has life without the possibility of parole.
Florida has used LWOP sentencing to replace capital punishment. As a result, it currently has the highest number of inmates serving life without parole, nearly a quarter of the total LWOP prison population nationwide.”
“Florida no longer has a traditional parole board. Instead, once a prisoner becomes eligible for parole, the Florida Commission on Offender Review (FCOR) decides on whether they will be released or not.”
Talk about shocking: “There are multiple states where a prisoner under certain circumstances can become eligible for parole after 2 years served of a life sentence. Often these variable life sentences are given for crimes that require additional rehabilitation or stricter parole.”
Life sentence lengths differ across jurisdictions, guided by state laws. Find the shortest and longest possible life sentence for each state.
