An ex-convict suspected of gunning down a New York police officer and then fatally shooting a carjacking victim is charged with first-degree murder.
Police officers packed the courtroom for Darrell Fuller's appearance Thursday in Hempstead on Long Island.
Authorities say the Queens man had been hospitalized until Wednesday for self-inflicted gunshot wounds.
Fuller is accused of killing a policeman who suspected he had been involved in a hit-and-run car accident on Tuesday.
Authorities allege Fuller then fled that shooting and killed the second victim while stealing his vehicle.
The name of Fuller's attorney was not immediately known.
Meanwhile, a second man has been arrested in connection with the shootings that resulted in the deaths of a New York policeman and a carjacking victim.
Nassau County Assistant District Attorney Mitchell Benson says the man is accused of trying to assist the suspected gunman after the shootings.
Prosecutors in the neighboring borough of Queens say Gerald Williams was arrested on weapons possession charges.
Fuller served four years in prison after pleading guilty to attempted murder in 2005.
A funeral for Nassau County Officer Arthur Lopez is planned for Saturday.
