Steven Eastwood, 28, was fatally shot by Southampton Town Police on May 10 after officers responded to a 911 call from his mother, who reported he was intoxicated and acting violently inside their Northampton home.
The woman survived the attack, Suffolk County police confirmed on Tuesday.
Officials previously said responding officers saw Eastwood in the house with the knife and attempted to de-escalate the situation. Body camera footage from multiple officers shows them yelling “drop the knife” several times while he is seen with what appears to be his mother's blood on his sweater, sleeves, and hands.
“Got one at gunpoint, send more units,” an officer can be heard saying over the police radio.
Body camera footage shows Eastwood briefly stepping out the front door with a knife in hand, pausing to stare outward before turning back inside. He is then seen moving into the room where his mother lies on the floor, where authorities allege he continued the attack, as she can be heard intermittently moaning.
According to the Attorney General’s Office, two officers fired their service weapons after Eastwood allegedly continued the attack on his mother.
He is then seen falling to the ground next to her, where he was later pronounced dead.
At a press conference following the shooting, officials said officers shot Eastwood to end his attack on her.
The Attorney General’s Office says several knives were recovered at the scene.
Three Southampton Town Police officers were reportedly injured during the incident but have since recovered.
Under state law, the Attorney General’s Office is required to investigate cases where police actions may have resulted in a person’s death.
