(Richmond, IN)--It was one year ago Thursday that a large industrial fire broke out at the My Way Trading site in Richmond. Thousands were forced from their homes as billowing black smoke rose from the scene of the My Way Trading fired that could be seen for miles.  In the months that followed, lawsuits were filed including a class-action suit against the City of Richmond and another claiming that a New Paris woman died as a direct result.  The EPA completed its cleanup last month.  "Spent about $2.8 million in federal superfunds, so no city dollars were spent," said Richmond Mayor Ron Oler  What has not been addressed in the year is the cause.  It is widely assumed to have been arson, but no law enforcement agency has ever released any information about where the investigation stands.
