"That sound is no joke, when I heard that I knew something was up," said Wilner Nau, an eyewitness.
It was the squeal of 36-year-old Kerline Denizard holding onto life that rattled Wilner Nau so much he ran outside in the darkness.
"When I went there she was on the ground, she had her bag near, her jewelry, even her shoes, and there was so much blood," Nau said.
Denizard was headed to first, pick up her sister, then to work around 5 o'clock Tuesday morning when police say a man in hoodie ambushed her as she got into a silver Maxima on 121nd Street in Queens Village.
He slit her throat and was stabbing her repeated when another neighbor who was also on his way to work interrupted the attack.
"That guy is savior, because as soon as that guy stopped, that guy stopped doing what he was doing, and realized he had to stop, and he ran, but he ran over there and dropped her phone in that yard over there," Nau said.
"I called her and she got like this because she couldn't even talk, and I tried to grab her but she already fell, and then I told my wife to call 911," said Mackenzie Cayo, an eyewitness.
Mackenzie Cayo was coming home from work Tuesday morning when he interrupted the attack.
Denizard was barely breathing when Cayo got to her, but he stayed with her as the 911 operator told him what to do.
"They told me to keep talking to her, and try to touch her, and I was doing that calling to her, talking to her, saying 'Stay with me, God loves you,'" Cayo said.
Denizard was not robbed, and family members say she had told them she was being stalked recently.
"She believed that, but I don't know, I can't tell you," said Taylor Antoine, the victim's uncle.
But at this point, police don't know what sparked the attack.
"We have not been able to speak to her. She has severe cuts on her arms and legs," Police Commissioner Ray Kelly said.
Denizard has worked for the United Cerebral Palsy Association as an aide for the last eight years. Now it's hard for those who know her to see her in a position of weakness.
"Hope she be alright. From what I heard, hope she be alright," a coworker said.
"I see her, she's a really nice person," said Daliah Ricketts, the victim's neighbor.
"She's a friend of mine, I feel so bad, I couldn't even watch this," Nau said.
The victim was taken to North Shore University Hospital in Manhasset.
The suspect fled the scene. He was preliminarily described as a black male, tall, and wearing a black hoodie.
