A North Amityville man stabbed his girlfriend to death after she told him she wanted to break up, then killed himself Saturday night, Suffolk County homicide detectives said.

The 14-year-old daughter of the victim, Virginia Vasquez, was cut on her hand when she tried to help her mother during the stabbing, police said. Officers found the bodies of Vasquez, 32, and her boyfriend, Stephen Guillaume, 35, in the doorway of the couple's North Drive home after the 9:40 p.m. attack.

Police in a statement Sunday did not disclose details on injuries or a weapon.

The girl was taken to a hospital where she underwent surgery, police said. The couple's 4-year-old son was not harmed during the attack.

The daughter, a ninth-grader, "will be out of the hospital tomorrow," Vasquez's sister, Sandra Vives, 41, said Sunday. Had the girl not had hand surgery, "she wouldn't be able to use her fingers," Vives said. "She's starting to feel her fingers; she can move them a little bit," Vives said. "She's still in shock."

In September 2006, Guillaume pleaded guilty to third-degree assault, a misdemeanor. A three-year order of protection was issued, court records show, but the victim was not identified.

Guillaume had been sentenced to six months' probation in October 2010 after pleading guilty to criminal sale of a controlled substance, a felony, records show. He has prior convictions for criminal facilitation, criminal sale and possession of a controlled substance, attempted criminal possession of a weapon, and petty larceny.

Vasquez's family said Saturday night that she was a loving mother of four children: the 4-year-old boy, the 14-year-old girl and two other girls, ages 7 and 15.

Relatives had been excited about marking Vasquez's 33rd birthday Monday, said Vives, who was at the scene on North Drive off Route 110 on Saturday night.

"We should have been celebrating," she said.

Vives said she received a call earlier in the night from her niece, Vasquez's 14-year-old daughter, saying Vasquez's boyfriend had stabbed her and killed Vasquez. The couple had been together for nine years, Vives said.

The relationship had been fraught with tension, Vives said, adding, "She told me she wanted to leave him."

Family members said Vasquez, also known as "Bibi," grew up in East Flatbush, and had worked as a dog groomer.

Mahmoud Ismail, 50, Vasquez's stepfather, said: "She was a good mom who took care of all of her kids. We tried to make her leave him for a long time, and this is what happens."

Ismail said he saw both bodies slumped inside the North Drive home. The door was stained with blood.

Family members said the boyfriend was the father of the 7-year-old girl and the 4-year-old boy.

Vasquez "was always happy, laughing, and everything," Vives said. "She was always trying to help people."

In Facebook posts about Vasquez, whom Guillaume described as his wife, he once wrote: "i got a beautiful wife i love her to death."

Homicide detectives asked anyone with information to contact the Homicide Squad at 631-852-6392.
