A Chillum man was convicted Wednesday of first-degree felony murder in the slaying of a 58-year-old who was found stabbed to death in his apartment on New Year’s Day 2011, prosecutors said.

After a three-day trial, David Henry Wright, 30, was convicted of first-degree felony murder, robbery with a dangerous weapon and other related counts in the slaying of Ansel Donovan Whitelocke, prosecutors said. Prosecutors said 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 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, prosecutors said. 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. Wright, they said, is scheduled to be sentenced on Nov. 29 and faces a possible life term.

Wright’s defense attorney did not immediately return a phone message seeking comment.
