According to the New  York Post, the butcher said, “The family had too much,”  because he thought “their income (and) lifestyle was better than his.”

The bloody suspect was caught holding the kitchen knife he used during the Saturday night rampage inside the Sunset Park apartment where he had been staying with the victims, the source added.

The unidentified killer was nabbed as he fled out the front door by two detectives who happened to be investigating a robbery pattern nearby when they heard a radio report about a domestic dispute involving a knife and responded to the scene, the source said.

Inside, cops found a house of horrors in which all five victims were hacked to death and one — a 1-year-old boy — was decapitated, the source said.

The as-yet unidentified suspect is a cousin of the dead woman’s husband and a transient with a Chicago address who arrived at their home about a week ago, police sources said.
