Her case Her case generated national outrage when she was sentenced to 20 years ... Now marissa alexander could end up behind bars for 60 years...for the same crime. Channel 4's erica rakow has more on the state attorney's push to triple her sentence. 3 Though she's free right now -- a retrial is looming for marissa alexander...after her conviction was thrown out on an appeal. Alexander's case drew national attention in 2012 after she was sentenced to 20-years in prison for shooting a gun in the direction of her estranged husband and his two children. But the conviction was thrown out after an appeals court ruled the judge made a mistake in shifting the burden to alexander to prove she was acting in self defense. Alexander was found guilty of three counts of aggravated assault with a deadly weapon. Each count carries a 20-year sentence, but the judge ordered those sentences to be served concurrently. However...if she's convicted again ...state attorney angela corey wants to increase her sentence to 60 years. It's a possibility that has outraged her supporters."we just think it's completely outrageous, vindictive...an incredible harassment and threat against Marissa Alexander in an incident where she was in fear for her life and took the only action she saw possible." Meantime...a bill inspired by the Alexander case is set to be considered by state lawmakers. The so-called "warning shot" bill will be part of the upcoming legislative session. If passed, it would create an exception to the 10-20-LIFE law.. and could prevent someone from having to serve prison time if they were judged to have fired a "warning shot". But an attorney we spoke to said any change in the law might not affect alexander's case. Alexander's retrial begins in late July. Local attorneys say the possibility of a plea bargain can come up. That's a move Alexander did not make the first time around.
