According to the Essex County Prosecutor, officers approached the man identified as the husband, 30-year old Abdul Kamal.
The prosecutor's office says Kamal refused to comply with officers commands, refused to remove his hand from his pocket, and threatened the officers, one of whom sprayed him with pepper spray.
Authorities say that when Kamal continued to threaten the officers and kept his hand in his pocket, three officers shot at him, firing a total of 15 rounds.
Kamal was pronounced dead at the scene. No weapon was recovered.
The prosecutor's office says Kamal had a history of domestic violence and that the shooting by police was found to be justified.
The case is still to be presented to a grand jury after further investigation.
