A Southeast Washington man was sentenced to two concurrent life sentences in jail yesterday after pleading guilty in Prince George's Circuit Court to the first-degree murders of his former girlfriend and her companion in July at her Fort Washington home.

Mark Allen Moore, 22, who was once employed as a hotel maintenance worker, admitted to the premeditated killing of Angela Benita Bellamy, 19, of 13100 Piscataway Drive, in Judge Howard S. Chasanow's court after the prosecution agreed not to seek the death penalty.

Assistant State's Attorney Margaret N. Nemetz said that Bellamy was bludgeoned to death after Moore, believed to be her former boyfriend, forced open the back door of the Bellamy family's brick, split-foyer house in the early hours of July 23. He then used a gun he was carrying to shoot to death Bellamy's companion, Hugh Knight Jr., 22, of 6408 Halleck St. in District Heights.

Moore was apprehended later the same morning at his 704 12th St. SE home by D.C. police.

Nemetz said that prosecutors decided not to seek the death penalty because of mitigating circumstances in the case. Defense attorneys cited such factors as Moore's previously clean criminal record, a finding by two psychiatrists that he had a mental disorder at the time and the fact that he was under the influence of the drug PCP at the time of the shooting.
