Son fatally stabs dad, victim stumbles out of NYC building then collapses on sidewalk: cops

A 58-year-old Harlem man stabbed in the neck by his own son stumbled out of his building and onto the sidewalk — where the mortally wounded dad collapsed, cops and prosecutors said Wednesday.

The older man – who was not immediately identified by police – died several days after he was stabbed by his 24-year-old son Lamont Oliphant around 11:45 p.m. July 20 inside an apartment within NYCHA’s Rangel Houses on Harlem River Drive near Frederick Douglass Boulevard, authorities said. 

The gravely wounded man managed to stumble out of the apartment, down the hallway, into an elevator, through the lobby and finally onto the sidewalk — leaving behind a trail of blood, prosecutors said in court.

He was rushed to Harlem Hospital, where he was placed in a medically induced coma and underwent a surgery that lasted multiple hours for a torn artery in his neck, according to a Manhattan assistant district attorney.

About an hour-and-a-half after the knifing, Oliphant — who was clutching a knife in his hands and had dried blood on his leg — brazenly approached cops standing outside the building and said he was trying to get back to his apartment, prosecutors said.

He provided his exact apartment unit, which is the same one where the trail of blood began, the DA’s office said.

Oliphant was arrested and charged with attempted murder and felony assault, according to the initial complaint. He was ordered held on $100,000 cash bail or $200,000 bond during a July 22 arraignment on those charges, prosecutors said.

The wounded man’s condition deteriorated for more than a week before he succumbed to his injuries on Friday, police said. His death was ruled a homicide by the city medical examiner’s office.

On Wednesday, Oliphant was arraigned on an upgraded top charge of second-degree murder and ordered held without bail, according to the DA’s Office.
