Employee fatally shoots robbery suspects at Auburn Gresham store

CHICAGO (WLS) -- Two teenagers, allegedly trying to rob a liquor store in the Auburn Gresham neighborhood, were fatally shot by a store employee Saturday night, police said.

William Larson, 17, and Keshawn Marzette, 15, were pronounced dead at 8:30 p.m. after police responded to reports of a robbery at the Z & S Food and Liquors in the 1300-block of West 87th Street on the South Side.

Police said the two men allegedly walked into the store, announced a robbery and one of the suspects pulled out a gun. The employee then allegedly took out his own gun and fatally shot the two suspects, police said.

Police say this is not the first time an incident like this has happened at the store.

In August 2011, the owner exchanged gunfire with suspects inside the store. One of the suspects was killed and the other fled the scene.
