A 37-year-old New Bedford man has been charged in connection with the slaying six years ago of a Dartmouth antiques dealer.

Authorities say Derek Hunt was indicted by a grand jury on Friday on murder and firearms charges in connection with the May 2003 shooting of 41-year-old Joseph Downing Jr.

Downing worked at a New Bedford glass company and was a part-time antiques dealer.

He was found dead in his minivan in the parking lot of a Dartmouth apartment complex.

The Bristol district attorney's office says Hunt is being held pending an arraignment in April.

Prosecutors did not provide a possible motive for the slaying.

District Attorney Samuel Sutter says the indictment is in line with his campaign promise to solve cold cases.
