Marissa Alexander freed!

Marissa Alexander, a Florida woman who says she fired a warning shot at her abusive husband was released from a Jacksonville jail on Tuesday under a plea deal that capped her sentence to the three years she had already served.

Marissa Alexander, 34, was initially sentenced to 20 years in prison in 2012 but her conviction was later overturned. She faced another trial on charges that could have put her behind bars for 60 years before she agreed to a plea deal in November.

Her case helped to inspire a new state law permitting warning shots in some circumstances.

Leaving the courthouse, Alexander cried as she thanked her supporters, sharing plans to continue her education in order to work as a paralegal.

Sharpton Leads March Over 'Stand Your Ground' Law

The Rev. Al Sharpton led several hundred people on a march Monday to the state Capitol, where they rallied against Florida's "stand your ground" law.

Among those present were the parents of slain teenager Trayvon Martin and the family of Marissa Alexander, who was sentenced to 20 years for firing a gun near her estranged husband. The crowd rallied on the Capitol steps across from Florida's Supreme Court.

"To have laws that tell people that they can shoot first and then ask questions later is a violation of our civil rights. I believe that law is inherently wrong," Sharpton said before the march began. "The law in effect says based on your imagination — if you imagine I'm a threat — you have the right to kill me."

Sharpton called Florida "ground zero" for the fight against 'stand your ground.'
