A 28-year-old Long Island man died in his father’s arms as his shocked mom looked on following a hookup gone horribly wrong early Monday, officials said.

Kristin Sculley, 22, who is facing second-degree murder charges in the fatal Massapequa stabbing of Robert Carragher, allegedly snuck into the victim’s basement apartment in the middle of the night for a pre-arranged liaison before stabbing the victim to death in his own bed, police said.

In a chilling moment, Sculley flashed a sinister smirk as she was led to court by cops on Tuesday.

“We believe that this female individual made an arrangement,” Nassau County Police Detective Lt. George Darienzo told reporters. “She was an acquaintance of our victim, who made an arrangement to get together that evening.

“The location of the stabbing is initially believed to be in the bedroom at that location,” Darienzo said. “The individual died in his father’s arms. No family should ever have to bear witness to the sudden killing of their son.”

Cops said Sculley allegedly “became angry” and stabbed the victim with a pocket knife.

The two had “a friendship” and knew each other “for several years,” the detective said.

Police were called to the Beaumont Avenue home around 1:30 a.m. Monday and walked into the grisly scene. They said the mortally wounded victim managed to get to his parents.

“He climbed the stairs to seek the assistance of his mother, screaming,” Darienzo said. “His mother and father came to his aid. They attempted to control that bleeding in the kitchen. At that point their son became unresponsive.”

He said there was evidence that the victim and suspect had been doing drugs, but none where found.

Sculley was arraigned on a second-degree murder charge in Hempstead court Tuesday afternoon and ordered held without bail at the Nassau County jail.
