NEW YORK — An 8-year-old boy was fatally stabbed in Queens Thursday, and the knife-wielding suspect was shot and killed by officers, the New York City Police Department said.

The stabbing likely stemmed from a domestic dispute, police said, but the details were still unclear. Police said the 20-year-old suspect and the 8-year-old male victim may be brothers or step-brothers. No names were immediately released. 

The incident occurred inside an apartment building on 94th Avenue in the borough’s Jamaica neighborhood. Around 5:20 p.m. local time, police say a 29-year-old woman who had been stabbed in the back left the building and walked down the street to MTA Police to ask for help. At the same time, the building’s security desk called 911.

Officers responded within three minutes and went to a fifth-floor apartment after speaking to a witness, police said.

Officers entered the apartment to find the suspect holding his 43-year-old father at knifepoint, police said, and the suspect refused repeated commands to drop the knife.

An officer then fired one round, striking the suspect, police said. Officers immediately rendered aid, and the suspect was taken to an area hospital, where he died.

According to police, an 8-month-old baby was also in the apartment at the time of the incident, but the baby was unharmed.

Footage of the shooting was captured on police body cameras. 

The investigation is ongoing.
