How Long Was Laurie in Prison?

Laurie's finger prints were not in the system, given that they would have been added to data basis if she were arrested. This seemed to rule out the crime theory. Even if she changed her name, her identity, when you are processed for prison, you are finger printed. So she can't run from that in terms of changing her name. If laurie had been convicted and tence for a crime that would land her in jail for more than 30 years. That's 402 months.
