A 23 year-old woman was murdered in a New York City apartment - her head nearly decapitated - after a heated argument with her black Hispanic boyfriend

Sarah Coit was heard arguing with Raul Barrera, 33, shortly before she was viciously stabbed in her apartment, cops and neighbors said. "Her whole neck was cut all the way," said Briana Andalore, 20, who lives downstairs from the blood-stained apartment and saw the young woman get hauled away on a stretcher. "Her head was almost cut off." The roars of their fighting echoed from their apartment for about 20 minutes, neighbors said. "I heard them arguing," said Jason Figueroa, 15, who lives just above the woman's apartment. "She was arguing with her boyfriend." Figueroa, who appeared shaken by the incident, said he could hear Coit, who grew up in Connecticut, being attacked, so he called the police. "She was like 'Stop, get off of me,'" he said. "And she was yelling and then she just got quiet," he said, "That's when I called 9-1-1." Authorities said that they responded to a call about a woman being stabbed and found Coit lying in a pool of blood. She was taken to hospital, where she died over an hour later. Barrera turned himself in after the vicious stabbing, police said. He was charged with second-degree murder. Neighbors said that the warring couple had lived in the apartment for about two years. They have heard the couple argue before, but it was not immediately known if police had ever been called to the residence.
