The two people killed in a north-central Idaho gas station explosion last week have been identified; two others remain hospitalized. The Idaho Press reports the incident, which occurred last Wednesday afternoon, left two dead and four injured. Idaho State Fire Marshal Knute Sandahl said that two of the injured were airlifted to Washington hospitals, and the two others were transported to local hospitals by ground. Sandahl said that the two airlifted were gas station employees. Brandon Luther Cook and Wesley James Lineberry were killed by blunt force trauma caused by the explosion. A spokesperson for UW Medicine said that Donny Billeter was in satisfactory condition Monday, while Roxann Hubbs was in the intensive care unit at Harborview Medical Center in Seattle. The cause of the explosion is still under investigation. The gas station was located in Cardiff, a small town located about 70 miles east of Lewiston in Clearwater County.
