Former "Teen Mom" star Amber Portwood has been released from prison early -- nearly four years early.
After quitting rehab, Portwood was sent to prison in Indiana, but she's managed to get out after serving about a year and half of her original five-year sentence.
So how did she get early release?
Released on Parole
Amber Portwood was released on parole for an unspecified period of time, reports Us Weekly.
Parole is a conditional release from prison. A defendant is ordinarily sentenced to prison "with the possibility of parole" -- but an inmate doesn't automatically get reviewed for parole.
After serving a designated percentage of her sentence, Portwood likely requested a review by the parole board to grant her early release. She most likely filed an application to get the process started.
The parole board likely accepted Portwood's application (which it had the option to reject), and a hearing was scheduled. The hearing was the reality star's time to shine: It was Portwood's opportunity to prove that she's been rehabilitated and is no longer a danger to society.
Though it's not a formal court hearing with lawyers and a trial, there is still an opportunity to present a case for parole.
Good Behavior Credit
Many inmates follow Portwood's footsteps and seek an early release from incarceration for good behavior.
In the former reality star's case, she "earned a combination of earned credit time for good behavior and completion of a substance abuse program, which resulted in her period of incarceration being reduced," reports Us Weekly.
In fact, from the prison's perspective, Portwood was not released early -- her period of incarceration was merely reduced because of earned credit.
Parolees are subject to a list of conditions. Typically, they must meet with a supervising officer, attend counseling and rehab, hold a job, and/or not break the law. If they fail to comply with the rules of parole or probation, they can be thrown back behind bars.
In this case, the former "Teen Mom" star will also be subject to random drug testing, reports Us Weekly.
Here's hoping the newly free young mom doesn't repeat history and resists unlawful temptations. For starters, she may want to steer clear of starring in a reality show.
