Rashad Tavon McMillan was 16 when he was killed on a cold morning in Upper Marlboro, Maryland. He was found behind a building on Addison Road with a fatal gunshot wound to his upper body; accounts say he was first shot in the face and then again, execution-style, in the back of the head. The shooting occurred on December 11, 2008.

Investigators reported the killing was retaliatory. Two months earlier Rashad’s cousin had stabbed a young man named Demarqus Moore. Moore, then 18, is said to have lain in wait behind bushes on the morning of December 11 and ambushed Rashad as he passed. Moore was arrested and charged in connection with the killing; a Prince George’s County jury later found him guilty of first-degree murder and he faced life in prison without parole.

If anyone knew Rashad, his routines, or saw activity near Addison Road that morning, please come forward with what you remember.
