A District man awaiting trial in a federal drug case was charged Friday in the long-unsolved shooting deaths of two men in Northwest Washington.

Gezo Edwards, 38, who was indicted and jailed a year ago on cocaine-trafficking charges, is alleged to have shot the two victims execution-style May 1, 1998, in the 1400 block of Euclid Street NW. Police formally charged Edwards at the D.C. jail Friday.

Authorities said Edwards killed one of the men, Che Chamberlain, 21, because Chamberlain was involved in a dispute with an acquaintance of Edwards’s. He allegedly shot the other man, Joseph Tollerson, 40, because Tollerson happened to be standing with Chamberlain.

Authorities said detectives obtained an arrest warrant in the killings based on information provided by witnesses after the shooting and on evidence obtained recently from accused criminals who have entered into cooperative agreements with police.

As of Friday, Edwards had not appeared in D.C. Superior Court to enter a plea in the homicide case.
