A man went on a knife attack, killing four relatives, including two children, at their New York City home. He then set the building on fire and stabbed two police officers before being shot. The incident occurred in Far Rockaway, Queens. The police officers were responding to a 911 call from a young female who reported her cousin was killing her family. The suspect, identified as Courtney Gordon, had been visiting the family from the Bronx. This incident follows a similar knife rampage in the Bronx last week.
