“[T]hree-strike laws” impose a life sentence on persons who have been convicted of three or more serious crimes. However, the definition of serious crimes depends on the each state. In most states, all three must be violent crimes. But in some states, this is not the case. California law mandates the life sentence for any third felony conviction so long as the first two were deemed “violent” or “serious.” Moreover, an individual can receive multiple strikes from a single incident, leading to unexpected life sentences.
In Rummel v. Estelle, the Supreme Court upheld a life sentence with the possibility of parole for William James Rummel for a felony fraud crime amounting to $120.75. On his third offense, Rummel refused to return money received as payment for unsatisfactory repairs of an air conditioning unit, resulting with a life sentence. In Lockyer v. Andrade, Leandro Andrade received a mandatory sentence of 25 to life for stealing a total of nine videotapes at two different K-mart stores. (source)
