Raphael Vasquez was also injured during the shootout last week in Garfield.
Police say Vasquez shot an undercover detective during an apparent robbery in the midst of a drug operation. He was then shot and wounded by another officer.
Vasquez is being held on $2 million bail.
Two other suspects, Melvin Guzman and Patrick Morel, appeared in court previously, pleaded not guilty and are being held with bail set at $750,000 for each.
Vasquez faces charges of first-degree attempted murder, first-degree attempted robbery, second-degree aggravated assault, second-degree possession of a firearm as a convicted felon, second-degree unlawful possession of a weapon and second-degree possession of a weapon for an unlawful purpose.
