On Monday night, the family of a New York City police officer who was killed in Ballantyne is outraged with the Charlotte-Mecklenburg Police Department and the District Attorney's Office.

The family told Eyewitness news it got a call on Friday from the DA's office about a possible plea deal for Carole Larossa.

WSOC first reported in April that investigators believe James Larossa was stabbed to death by his wife, Carole Larossa.

His family told Eyewitness News it's upset about a possible plea deal of voluntary manslaughter, which could mean less time in prison.

It's been eight months since police say an argument turned deadly between Carole Larossa and her husband, James Larossa. Police said she stabbed him 19 times, and ever since, the former NYPD officer's family has been fighting for justice.

"If I truly believed that my uncle had in any way been harming my aunt throughout the duration of their relationship as I knew them, I would back her," said James Larossa's niece, Lauren Cox.

Carole Larossa was originally charged with first-degree murder. According to the police report, she claimed she did it in self-defense.

Most of James Larossa's family is in New York. WSOC talked to Cox via Skype. Family members said the District Attorney's Office told them Carole Larossa was offered a plea deal on Friday.

That launched a firestorm of emails and phone calls to the DA's office and even Channel 9.

"We're devastated. We've remained silent since my uncle's murder on April 10," said Cox.

Cox's father, a former NYPD detective, sent a scathing email to the DA's office, blasting it and CMPD for how the case was handled.

The family has gone through great lengths to get the word out about the case.

There's also a Facebook page and a blog.

One of the recent blog posts says, in part, "Now is the time to stand up and have our voices heard. Jimmy no longer has a voice."

James Larossa' family is asking everyone to write their congressmen.

"We had no doubt in our mind that they were going to do what was needed to bring Carole to justice," said Cox.

In response, the Police Department said it can't comment on a pending case. CMPD arrested Carole Larossa on suspicion of murder.

The DA's office wouldn't comment on the email or confirm if Carole Larossa has accepted the plea deal. Her lawyer didn't respond to WSOC's request for comment by news time.
