BANGOR — A South Dakota man has been indicted in the death of a homeless man whose body was found engulfed in flames under a downtown bridge in Bangor more than four years ago.

Bangor police say a Penobscot County grand jury today indicted 25-year-old Kenneth John Bruning of Rapid City, S.D.

Police said Bruning is in jail in Rapid City on unrelated charges and will be extradited to Maine.

He is charged with murder in the March 7, 2006  death of 34-year-old Trevor Sprague. Sprague, who was from Lubec, had been living in Bangor at the time of his death.

Bangor police said once Bruning is returned to Maine, an affidavit will be filed outlining additional details in the case.
