Attorneys for Marissa Alexander are asking for a Stand Your Ground hearing to argue that she fired a shot at her estranged husband in self defense.

It will be the second time Alexander, 33, seeks immunity from prosecution under the states Stand Your Ground law, which allows the use of deadly force instead of retreating if the person is afraid for his or her life. A previous claim in July, 2011 was rejected.

Alexander, 33, is out on bond while awaiting a new trial on charges of firing a gun at her estranged husband and his two children. She was previously convicted of three counts of aggravated assault with a deadly weapon and sentenced to 20 years in prison, but that conviction was thrown out on appeal.

The new Stand Your Ground motion, filed Friday by attorney Bruce Zimet, argues that there is critical new information that wasnt heard in the original Stand Your Ground hearing. It also says the information presented at the original hearing was at best grossly incomplete.
