(CNN) -- Saying he had no discretion under state law, a judge sentenced a Jacksonville, Florida, woman to 20 years in prison Friday for firing a warning shot in an effort to scare off her abusive husband.
After the sentencing, Rep. Corrine Brown confronted State Attorney
Angela Corey in the hallway, accusing her of being overzealous, according to video from CNN affiliate
WJXT.
"There is no justification for 20 years," Brown told Corey during an exchange frequently interrupted by onlookers. "All the community was asking for was mercy and justice," she said.
Corey said the case deserved to be prosecuted because Alexander fired in the direction of a room where two children were standing.
Alexander said she was attempting to flee her husband, Rico Gray, on August 1, 2010, when she picked up a handgun and fired a shot into a wall.
She said her husband had read cell phone text messages that she had written to her ex-husband, got angry and tried to strangle her.
She said she escaped and ran to the garage, intending to drive away. But, she said, she forgot her keys, so she picked up her gun and went back into the house. She said her husband threatened to kill her, so she fired one shot.
"I believe when he threatened to kill me, that's what he was absolutely going to do," she said. "That's what he intended to do. Had I not discharged my weapon at that point, I would not be here."
Alexander's attorneys tried to use the state law that allows people to use potentially deadly force anywhere they feel reasonably threatened with serious harm or death.
But a previous judge in the case rejected the request, saying Alexander's decision to go back into the house was not consistent with someone in fear for her safety, according to the
Florida Times Union newspaper.
A jury convicted Alexander in March and Judge James Daniel denied her request for a new trial in April.
Daniel handed down the sentence Friday after an emotional sentencing hearing during which Alexander's parents, 11-year-old daughter and pastor spoke on her behalf.
