RALEIGH — Police investigators obtained a DNA sample from a 21-year-old man charged with murdering a woman in her North Raleigh apartment on Jan. 20.

Angel D. Irby, a native of Chicago who had recently moved 201-20 Loft Lane in Raleigh, was found dead after Wedjunald Gemielle went to the Fountain of Raleigh Fellowship on Six Forks Road during the congregation’s Sunday service and told a retired Raleigh police detective that he had murdered his “girlfriend,” according to search warrants made public this week at the Wake County Clerk of Courts Office.

Irby’s family members she was dating one of Gemielle’s friends, not Gemielle.

Investigators have not yet revealed how Irby died or where she was found inside of her apartment, but search warrants indicated that police confiscated a fitted bed sheet, pillows, a top sheet and a blanket from her home. They also seized two mobile phones from Gemielle’s 1997 Infiniti J30, court records show.

Gemielle is being held without bail at an undisclosed location for safekeeping after he was charged with assaulting a public official at the Wake County jail on Jan. 22, authorities reported.
