An 18-year-old who a friend said was about to begin his senior year at Ballou High School was one of two young men fatally shot in the District early Saturday morning.

Police said Shaun Simmons, of Southeast, was shot multiple times in the 1300 block of Savannah Street SE in Congress Heights, at about 4 a.m. He was found lying in the street and was taken to an area hospital where he died of his injuries.

About an hour earlier, Michael Toland, 22, of Northeast, was fatally shot in the 4600 block of G Street, off Benning Road in Southeast, about six blocks from the Maryland state line. He was shot in the back and leg, according to a police report.

Police have not said if the slayings are related, and no suspects have been identified, said Officer Sean Hickman, a D.C. police spokesman.

The shootings, which push the District’s homicide count to 86, come during an uptick of violence in the city that has concerned police and other officials.

Through the end of July, there were 84 people slain in the District in 2015, compared to 69 in the same period last year. At a recent news conference, Police Chief Cathy L. Lanier said other cities also are experiencing an increase in violence.

Anastasia White, a friend of Simmons, said he enjoyed football, wanted to go to college and planned to join the Job Corps after high school.

“He really was a caring and loving person,” White said. “He always did this smile when people were sad or angry and it would just make your whole day.”
