How Many Years is a Life Sentence in Jail?

The number of years for a life sentence in jail does not necessary mean the life of the convicted. The life sentence is given when there has been a serious felony crime for example first degree or serial murder especially if aggravating factors are present. The actual time a convicted felon spends in jail on a life sentence varies by jurisdiction and depends also on the Board of Parole that reviews and approves the appeals for parole.
