Fires that have destroyed homes costing as much as $600,000 have raised suspicions that an arsonist who doesn’t like some developments in St. Louis might be at work. Firefighters battled huge fires only about a half hour apart on Wednesday, fires that did $4.5-Million damage. Investigators worry the two fires might be connected with an April 27th fire that did $3-Million damage to Compton Gate, a high-dollar condominium development. That fire has been determined to be arson. Investigators will be testing for traces of chemical accelerants to determine if the latest fires were set.
