Marissa Alexander

Marissa Alexander could wind up back behind bars today if a judge decides to revoke her bond for running errands.

Alexander, 33, was sentenced to 30 years in prison for firing what she called a “warning shot” at her estranged husband who was at her home to pick up their son. The prosecution had argued that Alexander stalked her ex-husband because she had trouble letting go.

Alexander was convicted of aggravated assault with a firearm. But in September, an appeals court ordered Alexander released on $150,000 bond after her case received worldwide news coverage.

The appeals court ordered a new trial for Alexander, because the jury received improper instructions regarding her Stand Your Ground defense. The new trial is set for March.

Alexander was released in November to home detention with strict conditions regarding her movements. But she violated the conditions of her house arrest by running “errands.”

A judge will decide on Friday whether to throw Alexander back in prison.

“She continues to demonstrate her utter disregard for conforming her behavior to the rules … [others] must abide by,” state prosecutors wrote in a motion filed Tuesday.

Alexander’s lawyers argued that the state’s attorneys knew she received permission to run household errands. It isn’t clear who gave her the permission.
