PENNSVILLE — The man authorities say stabbed is stabbed his wife to death while their children slept — found by police standing her body, covered in blood — called 911 to report "She is not breathing properly.

Audio recordings of the 911 call Nitin Singh made Tuesday were first published online by NJ Advance Media. In the call, Singh repeatedly says of wife Seema, "My wife is not breathing" and "She is not breathing properly."

Chief of Police Allen J. Cummings has previously said the killing appeared to be the product of a domestic dispute between 46-year-old Nitin Singh and 42-year-old Seema Singh.

Police say they arrived at the couple's North Broadway home in response to reports of a person with a respiratory emergency. When officers arrived, they found Seema Singh on the kitchen floor with multiple stab wounds and her husband standing over her, covered in blood, police say.

Officers also awoke the three children, ages 6 through 16, and took them out of the home, steering them away from their mother’s dead body, police said.

Nitin Singh was questioned by police and later arrested and charged with the murder. He is being held in the Salem County Correctional Facility in lieu of $1 million full cash bail, police have said.

In the 911 call, an operator asks Nitin Singh if his wife is conscious and alert. He tells her "No" and "She's unconscious."

"But she is breathing?" the operator asks.

"I don't know. I can't tell you," he answers.

After Nitin Singh gives the operator his name, she asks: "Can you tell if she's breathing by looking at her? Can you tell if she has a pulse?

"She's unconscious," he says.

"I got that she's unconscious. I'm trying to find out if she's breathing," the operator says. "Can you see if she's breathing?"

She's not, he answers.

"Do you know how to do CPR? Do you want to do CPR?" the 911 operator asks Nitin Singh.

"No, can you send help, please?" he says.

The call cuts off a moment later.

According to an NJ Advance Media account of the recording, the 911 center repeatedly tried to call back, but no calls were answered, and some went to voicemail.

The article cited Police Allen J. Cummings saying an autopsy showed Seema Singh had been stabbed more than 30 times.

Nitin Singh has been charged first-degree murder, second-degree aggravated assault, fourth-degree unlawful possession of a weapon and fourth-degree possession of a weapon for an unlawful purpose, according to Pennsville police.
