The man convicted in the slaying of a 58-year-old man, who was found stabbed to death in his Chillum apartment on New Year’s Day 2011 was sentenced to life in prison Thursday, authorities said.

David Henry Wright, 30, had been convicted in September of felony first-degree murder and other related counts in the slaying of Ansel Donovan Whitelocke. As part of his sentence, he will not be eligible for parole, said Nancy Lineman, a spokeswoman for the Prince George’s County State’s Attorney’s Office.

Prosecutors have said previously that Wright participated in an unusual scheme with two others to rob Whitelocke, and that he stabbed Whitelocke 43 times when Whitelocke refused to give up money. The others involved, prosecutors said, already pleaded guilty to their roles in the incident.

By prosecutors’ account, the incident began on Dec. 31, 2010, when a woman, Verlyncia Coleman, and a female friend went to Whitelocke’s home in the 5700 block of Cypress Creek Drive in the Chillum area. Police had said previously that Whitelocke knew Coleman because he had paid her for sex. Prosecutors said she hatched a plan with Wright and another man, DeMarco Williams, to rob him.

Seconds after Coleman and her friend left, prosecutors said, Wright and Williams came into Whitelocke’s apartment and demanded money. When Whitelocke refused, Wright stabbed him, prosecutors said. He and Williams fled with a Bible, jewelry and about $550 in cash, prosecutors said.

Williams had previously pleaded guilty to first-degree murder, Coleman to conspiracy to commit first-degree murder, prosecutors said. Williams was given a 45-year prison sentence, Coleman an 18-year sentence, prosecutors said.
