as her two daughters looked on, authorities and family members said Sunday.

Stabbing victim Toribia Henriquez was taken to Lincoln Medical Center, where she died of her wounds.Willy Canturencia, 28, was so ruthless that after stabbing Toribia Henriquez, 35, in front of her children, he followed the dying woman into the hallway of their Mount Eden apartment building, where she collapsed in blood and repeatedly knifed her again, law-enforcement sources said.

The [older] daughter ran out and knocked on the neighbor’s door, screaming, ‘Help! My mother’s being stabbed!’ ” said a resident, Jamaira Gonzales, 34.

Cops said Henriquez and Canturencia got into a dispute in their Walton Avenue apartment just before 1 a.m. The enraged man then picked up a knife and plunged it into Henriquez in front of her two daughters, ages 17 and 2, sources said.

Gonzales, who lives two floors below the couple, said she could hear someone upstairs yelling, “Stop, man, don’t do that! Don’t kill your wife!”

Canturencia “was gone for about six months, and about a month ago, he came back around,” Gonzales said. “He drinks a lot. Maybe he was jealous about something.”

As Henriquez lay dead in the blood-covered hallway, her boyfriend turned the knife on himself, slitting his own throat and wrists in front of horrified neighbors, witnesses said.
The victim’s cousin recalled seeing Canturencia just minutes before the attack.

“I saw him downstairs smoking a cigarette, and then later, I heard yelling and running,” she said.
Police said that they had responded to five prior domestic incidents involving the couple and had arrested Canturencia each time.

The suspect was taken to St. Barnabas Hospital, where he was being treated for non-life-threatening injuries. He was charged with murder, assault, menacing and criminal possession of a weapon, police said.
