The high-profile murder conviction of a Dutchess County mother who claims she was the victim of domestic violence was back in court Thursday.

Nikki Addimando is appealing her conviction as the first case of its kind in the state.

Addimando has been imprisoned for two years since she was found guilty of fatally shooting her domestic partner and children's father, Christopher Grover.

On Thursday, her case was appealed in a virtual proceeding before four appellate court judges in Brooklyn.

"There are 4,000 women killed each year in the United States. Seventy-five percent of those that are killed, tried to leave attempting the so-called path to escape," says defense attorney Garrard Beeney.

The case was arguably complicated from the start.

"She made conflicting claims about Mr. Grover to different people in her life," said Putnam County prosecutor Larry Glasser.

The defense alleged Grover sexually, physically and emotionally assaulted Addimando for years. It even alleged Grover violently raped her and threatened to kill her the night of the murder.

One of the key points that the defense argued was the original judge's refusal to apply the Domestic Violence Survivors Justice Act, a new law that would have considered the alleged abuse and lessened Addimando's sentence.

Judges heard arguments for two hours Thursday, despite the fact appeals cases are normally no more than 15 minutes.

It could take up to a year for the judges to decide.
