News 12 has obtained exclusive video of last month's deadly hammer attack in Sheepshead Bay.
The video shows the suspect inside the Seaport Buffet, where he pulls a hammer out of a bag and hits a man.
Another part of the video shows the suspect going into what appears to be a kitchen area and striking again.
Three employees were killed in the attack -- a chef, the manager and the owner of the restaurant, who all died from their injuries.
Arthur Martunovich, 34, was arrested in the case and faces murder and hate crime charges. Prosecutors believe the motive was racial animosity toward Asian people.
Martunovich pleaded not guilty and is expected to have a mental health exam to see if he is fit to stand trial.
