A federal grand jury in East St. Louis has indicted 19-year-old Denzell Grant with interfering with commerce by robbery and illegal possession of a firearm. Grant pleaded not guilty during a hearing Thursday.
Authorities say Grant entered Mac's One Stop Shop in Swansea in October, pointed a handgun at a clerk and demanded money. Investigators say the two men struggled and the gun discharged.
Grant is based at Texas' Fort Hood but is from South Carolina.
A message left Friday with his federal public defender, Todd Schultz, was not immediately returned.
