A judge sentenced a 26-year-old D.C. man to 34 years in prison for killing a 15-year-old boy in 2015.
A jury convicted Derryck Decuir of second-degree murder and other charges in May.
On June 16, 2015, about 12:20 a.m., Decuir and the victim, Ballou High School student Malek Mercer, were at a bus stop when Decuir's friends teased him about looking at and commenting about Mercer's belt, prosecutors said. Mercer snickered.
The two rode the same bus for about 10 minutes. When Mercer got off, Decuir followed and shot Mercer in the back of the neck, prosecutors said.
Police officers responding to a 911 call found Mercer bleeding in the grass at 28th Street and Naylor Road in Southeast. He was taken to Washington Hospital Center where he died three days later.
Decuir was arrested the same day Mercer died and has remained in custody since.
Decuir previously was convicted of obstruction of justice for calling a friend from jail and asking him to hide the gun, prosecutors said. Police found the gun about a year later and linked it to Mercer's death.
