(Portland, OR)  --  The families of two men killed in an apartment fire over the Fourth of July weekend are suing the complex's management company.  The families of Robert Gremillion and Seth Thompson filed a lawsuit in Multnomah County Court Monday against the owner and manager of Heidi Manor as well as the apartment's contracted garbage and recycling company.  Gremillion and Thompson both died when fireworks inside a dumpster next to Heidi Manor sparked the fire that burned their building.  The families claim the management company didn't keep the building up to code to ensure the fire wouldn't spread as quickly.  The ATF is still looking for a suspect behind the fire.
