A 38-year-old man jumped to his death early Wednesday while trying to escape from an apartment fire in Columbia Heights that authorities believe was set intentionally.

The blaze broke out at the Sarbin Towers, located at 3132 16th St. NW, at about 3:45 a.m., D.C. Fire Chief Dennis Rubin said. Investigators said the fire originated in a fifth-floor hallway area of the eight-story, 63-unit building.
