Marquise Sampson was 19 when he died on July 8, 2012, in Chicago during a police encounter after an armed robbery at a King Gyros restaurant. Police say Sampson and an accomplice, Tevin Louis, also 19, robbed two employees at gunpoint, taking money, a cell phone, and cigarettes. Both fled; officers later spotted Sampson running through the Gresham district. According to police, Sampson held his side while running, ignored commands to stop, then pulled a gun and pointed it at an officer, who shot him twice. Sampson was pronounced dead at the scene and the coroner ruled the death a homicide.

Tevin Louis was arrested nearby and charged with first-degree murder, armed robbery, and disorderly conduct. Prosecutors used restaurant surveillance footage and victim testimony at trial; Louis was convicted and received a combined 32-year sentence (20 years for murder, 12 years for armed robbery). The case raises questions about application of the felony murder rule when the fatal shots were fired by police.

If anyone has information about Sampson, Louis, or the events outside King Gyros, please share what you know.
