Three men were slain in the District in a three-hour period late Saturday and early Sunday, police said.
Two of the victims were shot and one was stabbed. Each killing occurred in a different quadrant of the city. In each incident, a second person was wounded and taken to a hospital.
No obvious connection among the incidents could be found, but they all occurred on a particularly steamy night during a period of record heat.
Shortly before 10 p.m., two men were found in the 5300 block of Ames Street NE with stab wounds. Both were taken to a hospital. One was admitted, and the other was pronounced dead.
The dead man was identified as Charles Anthony Scott Jr., 20, of Northeast Washington.
Within an hour, a shooting was reported several miles away in the 1700 block of Seventh Street NW, in the Shaw area. Police said Michael Edward Jones, 30, of Northwest Washington died at the scene. A second gunshot victim was taken to a hospital and released after treatment.
Four minutes into Sunday, police said, a shooting was reported in the 1700 block of Galen Street SE. They said Davon Brown, 22, who had been shot at least twice, was dead at the scene.
Another man, who had also been shot, apparently in the same incident, was found in the 2300 block of Green Street SE and taken to a hospital for treatment.
No information was immediately available on suspects or motives in any of the incidents. Relatives of the victims could not be reached.
