Seth Sinquan Holmes was ordered held without bail, despite allegations of contradicting witnesses in his arraignment hearing.
Holmes was charged with second-degree murder while armed for allegedly killing 25-year-old Damonta Thompson in the 100 block of Irvington Street, SW, on May 9.
The defense motioned to have Holmes released to a halfway house, but their motion was denied.
Holmes is next scheduled to appear in court on July 20.
