The suspected assailant of a stabbing was immediately shot dead by one of his victims on the intersection of Sperry and Goffee Streets around 10 p.m Tuesday night, according to New Haven Police Department spokesman David Hartman.

Officers and EMTs were dispatched to the site of the gunfire once the assault was reported.

A 27-year-old New Haven man was walking on Sperry Street from Whalley Avenue “when he was confronted by an adult black man holding a knife,” according to Hartman. The knife-wielding man said “Happy Halloween” and stabbed the victim.

The victim’s cousin, a 24-year-old man from Hamden, Connecticut, was waiting in his car. Upon hearing the commotion, the victim’s cousin got out of his car, and was also stabbed by the assailant. The 24-year-old stabbing victim had a pistol on him and shot his assailant in the chest.

Hartman said the deceased assailant has not been identified.

In the press release, Hartman wrote that the shooter has a valid pistol permit and his gun was lawfully registered to him, according to information obtained in a police records check. The shooter has not been charged — though, according to Hartman, “this investigation is active and remains active.”

The 27-year-old was stabbed in the elbow, while the 24-year-old was stabbed in his bicep. The wounds of the victims are not life-threatening.

Officers and detectives from the police department’s Major Crimes and Forensics Division remain on the scene, and are investigating the crime and collecting evidence for the case.

Hartman ended his report by asking that anyone with information on the crime should phone the New Haven Police Department or send in an anonymous tip. He wrote that further updates on the case will be released to the press pool at large once it is prudent to do so.
