The fatal stabbing happened about 1:15 a.m. on the 1200 block of North Capitol Street NW, which includes the Tyler House apartment building.
Kenneth Eugene Jackson of Northwest D.C. was unresponsive when police arrived on the scene, according to authorities. He was brought to a local hospital, where he was pronounced dead.
Police haven’t released any suspect information.
The attack happened a week after a man was stabbed on the same block. That stabbing wasn’t fatal.
