Montclair police Lt. Brian Ventura said the victims appear to be shot execution-style, and their mouths were covered with duct tape when their bodies were discovered Sunday night.
He said the unidentified men were in their 30s, and one of them was handcuffed.
Witnesses told investigators a third person who was handcuffed and had duct tape around his mouth fled the scene. Ventura said that person also had a deep wound in the neck.
Investigators have not identified a suspect or a motive in the attack.
