14-year-old girl found slashed to death in her Queens bedroom

A 14-year-old Queens girl was found slashed to death Sunday afternoon inside her bedroom in her family's tidy home in Cambria Heights, cops said.

Sabrina Matthews' father walked into the teen's room about 1:30 p.m. to find her unconscious and naked from the waist down, with blood gushing from a wound to her throat, police sources said.

Paramedics frantically tried to revive the Martin Van Buren High School ninth-grader, but there was no hope.

She was pronounced dead about 1:30 p.m. inside the home on 234th St.

"Who could it be?" cried Delores Kelly, 53, Sabrina's aunt. "Who could kill my niece?"

Kelly said she had nicknamed Sabrina "Brains" because of her passion to learn.

"When I come to the house, she is always on the computer," Kelly said. "Always doing homework."

One of the slain girl's best friends said she had recently started hanging out with a rough group of boys.

"She promised me she was done with all those guys," said Laquan Jones, 18.

Sabrina's father, Livingston Matthews, 51, went to the 105th Precinct stationhouse for questioning yesterday.

Police said officers had visited the home at least three times during the past few weeks to investigate reports of domestic incidents.

One call involved the father in a screaming match with one of Sabrina's older sisters, police sources said.

The family was never reported to the Administration for Children's Services, which could suggest the other incidents did not involve the teen.

Neighbors on the treelined block said the Matthewses appeared to be a hardworking couple and had emigrated from Jamaica.

Sabrina had three older sisters - Anita, Candy and Latoya.

Their mom is a home health-care worker.

The father works as a driver for ACS.

Neighbors were stunned at the slaying.

"I could not believe it," said Cecile Garvey, 62, who lives down the street. "I was in shock."

Neighbor Bill Manning, 65, said he would not leave his home until he knew what was behind the macabre killing.

"It takes a lot of nerve to go into somebody's house and slit their throat," he said. "It's savage."
