CONCOURSE VILLAGE, the Bronx (PIX11)– Police said a domestic argument between an off-duty NYPD officer and her estranged husband turned deadly early Monday morning.

The rookie officer, 31-year-old Arianna Reyes-Gomez, was stabbed multiple times in the attack. She got the strength to call her cousin, who then called 911, but when police arrived, it was already too late.

Reyes-Gomez was found unconscious and unresponsive with multiple stab wounds on her body at an apartment in Concourse Village at around 2:50 a.m., police said. EMS pronounced her dead at the scene.

“We will remain with her family and her colleagues in support and prayer,” the Police Benevolent Association said in a statement. “We will see that justice is done in her name.”

The victim’s estranged husband, 33-year-old Argenis Baez, turned himself in to the police, officials said. He has been charged with murder, manslaughter and criminal possession of a weapon in the alleged attack.

The couple shared a 3-year-old son, who was not present at the time of the incident.

Sources told PIX11 News Reyes-Gomez was attempting to get away from Baez, but he allegedly wouldn’t let go. Neighbors said they never noticed anything out of the ordinary, but wish they had seen the signs sooner.

“I couldn’t really help to do anything, because I really didn’t know them,” neighbor Frank Peralta said, noting that the couple was “too closed off.”

The investigation is ongoing.
