Another suspect in the case, 31-year-old Newark resident Rayshawn Riddick, was arrested on September 14 by members of the FBI Task Force, New Brunswick police and Middlesex County Prosecutor’s Office, according to authorities.

Martin and Riddick were both charged on August 29 with one count of murder in the first degree, conspiracy to commit murder in the first degree and possession of  weapon for unlawful purposes in the second degree.

The charges stem from an August 18 incident in which Hakim Williams, a New Brunswick resident, was found shot to death inside his car on Fulton Street.

A neighbor called police after hearing gunshots, authorities said. Shortly after they arrived, at 11:03 p.m., Williams was pronounced dead at the scene, they said.

Authorities were also seeking Diana Williams, 26 of New Brunswick, because they believed she was with the two murder suspects, according to police. However, they are no longer actively searching her, prosecutor's said. 

The investigation is still ongoing and authorities are asking anyone with information to call New Brunswick Police Detective at 732-745-5217 or Middlesex County Prosecutor’s Office Detective Craig Marchak at 732-745-3254.
