Fire investigators are now interviewing possible suspects in an arson that happened at a plastics company in Longview several months ago.
Back in September, there was a third fire at Southwest Plastics since 2003. It happened September 22nd in the company's office, just weeks after one that destroyed the warehouse. From the beginning, investigators had their suspicions the fire was intentionally set. But now, after determining the fire an arson last week, ATF agents are focusing their efforts on a damaged surveillance tape for any possible leads.
