Peter Greene's cause of death confirmed as accidental gunshot wound

Peter Greene's death has been clarified after the shock news of his death caused by gunshot in his New York apartment was announced.

Greene, who is best known for his role in films like Pulp Fiction and The Mask, was found dead last week (12 December) with police revealing a note from within the home with the words 'I'm still a Westie' soon after.

The sentence is in reference to an Irish-American gang from the Hell's Kitchen neighbourhood of New York around 1960s to the '80s.

Greene's neighbours reportedly claimed seeing Greene 'lying on the floor, facedown, facial injury, blood everywhere,’ they told the New York Daily News, with police responding to his home at 3.25pm local time where Greene was pronounced dead at the scene.

According to reports, the neighbours had called police on Greene after hearing non-stop Christmas music coming from his apartment in the 24 hours before he was found dead, per Deadline.

While police revealed they weren’t treating his death suspiciously, the sudden death of the star left unanswered questions due to him reportedly being scheduled to undergo a benign lung tumour removal the day of his death. His agent had also confirmed some of the actor's upcoming projects.

Gregg Edwards, Greene’s manager, had previously shared with PageSix that his client was ‘in good spirits’ days before his death.

Now, the New York Medical Examiner's office has confirmed he was accidentally killed.

The office said his death was due to a ‘gunshot wound of left axilla with injury of brachial artery’ and an ‘accident’.

The axilla is located in the armpit, with the Cleveland Clinic stating the brachial artery is the major blood vessel that supplies blood to the upper arm, elbow, forearm and hand.

It states: “When you check your blood pressure, the cuff squeezes the brachial artery to get a measurement.”

As for the legacy he has left behind, Edwards said: "He was a terrific guy. Truly one of the great actors of our generation. His heart was as big as there was.

"I’m going to miss him. He was a great friend. He worked with so many amazing actors and directors."

He added: "We’ve been friends for over a decade. Just the nicest man."

Greene's most recent role was in the film, Clicka, which was released last month.

His manager also shared he had been working on a documentary at the time of his death called From the American People: The Withdrawal of USAID.
