Norbert Keene was the owner and operator of the Center Street Drug Store for fifty years from 1925 to 1975. He administers Eddie's asthma medication and later reveals to him that it's only a placebo.
Many years later, Mike interviews him and Mr. Keene tells him the story of the Bradley Gang, a group of outlaws who were hiding out in Maine after several bank robberies in the midwest. He tells Mike that, in 1929, a year before the fire at the Black Spot, the entire gang was murdered by Derry residents when stopping through town to buy ammunition. Mr. Keene says that rather than covering up the event, the whole town instead pretended that it never occurred, including police Chief Jim Sullivan, who even took part in the slayings. Finally, Mr. Keene mentions seeing a clown participating in the shooting, but that it was wearing farmer's attire rather than a traditional clown suit. He also points out that even though the Sun was out, the clown cast no shadow.
Pennywise later finds Eddie at the local pharmacy and proceeds to taunt him by possessing the elderly Mr. Keen and use him to tell Eddie to get out of Derry while he still could.
