A DNA expert testified, during a homicide trial Sept. 13, that blood was found on a shirt the defendant was last seen wearing.

Edward Brown, 61, is charged with first-degree murder while armed in connection to the stabbing death of 77-year-old Michael Mahoney on Feb. 5, 2018, on the 2300 block of 11th Street, NW.

Brown and Mahoney’s DNA were found on a black long-sleeve shirt and blue jeans that Brown was wearing in surveillance footage, said a DNA analysts who worked on the case.

Mahoney is last seen entering his apartment at 10:03 p.m, on Feb. 3 according to the Metropolitan Police Department’s lead detective on the case.

His notes stated that at 1:16 a.m, on Feb. 4, Brown is seen coming from the direction of Mahoney’s apartment and getting into the elevator; wearing a Redskins jacket, black long-sleeve shirt, burgundy and gold sock cap, blue jeans, and black shoes.

During cross-examination, defense attorney Kevin Mosley created reasonable doubt in the detective’s investigation. Mosley noted that several unidentified persons had interactions with the victim and Brown that detectives never tried talking too.

The prosecution called two more witnesses to the stand. Both were from Bode Technology, the first expert witness was a forensic biology analyst and the second was a senior DNA analyst.

The biology analyst testified to testing the Redskins jacket that Brown was seen wearing in the surveillance video, for blood. The jacket tested negative for any presumptive blood.

Mosley had the expert witness point out every spot on the jacket she tested for blood. The expert pointed to 11 areas that tested negative.

DC Superior Court Judge Rainey Brandt scheduled the trial to resume on Sept. 14.
