DENVER (AP) - An ex-convict suspected of planting a homemade bomb at a Denver-area shopping mall now faces a charge of using a destructive device, in addition to arson.
A grand jury late Thursday handed up an indictment against 65-year-old Earl Albert Moore. The indictment replaces charges filed by prosecutors. Moore is due in court Friday afternoon.
Moore is accused of starting a fire at Southwest Plaza Mall on April 20, which raised fears the incident was connected to the anniversary of the Columbine shootings. The mall is about two miles from the school where 13 people died in 1999 and makeshift explosives - a pipe bomb and two small propane tanks - bore some similarities to the attacks.
Authorities say the fire is unrelated to Columbine, but haven't released a motive.
