Police were called to the 500 block of North 9th Street around 9:30 a.m. Tuesday.
The Camden County prosecutor's office said the victim, 27-year-old Madaline Morales, was found stabbed and pronounced dead at the scene.
Her friends told Action News that Morales was a mother of four children.
Jose Quinones, 36, of the 600 block of North 9th Street, was also found at the home suffering from stab wounds.
Investigators say Quinones is a former boyfriend of the victim Morales, and she had filed a temporary restraining order against him on April 15th.
Friends say there was a confrontation at the house on Tuesday morning. The door was locked as the homeowner frantically tried to get back into her house.
"I saw her trying to get in her door and, at first, I thought she locked her kids in there," said neighbor Anita Green. "She was screaming. Then a guy finally pried the door open with a crowbar, she went in and, when she came out, she was screaming."
Inside, Morales and Quinones were found stabbed.
"When I went there both of them were laying there. It was gruesome, they were covered in blood. He was on his back, she was on her side," said Patricia Sturdivant. "Three minutes later I looked and he was rolled over, so I said 'He's alive! He's alive!"
Quinones was taken to Cooper University Hospital and was last reported to be in surgery.
