AUSTIN, Texas -- State officials say an investigation into the fertilizer plant explosion in West should be finished within two weeks.
Texas State Fire Marshal Chris Connealy told lawmakers at a legislative hearing Wednesday that his office is targeting May 10 for investigators to complete their probe into the origin and cause of the fire and explosion at West Fertilizer Co.
Authorities have not hinted what might have caused the April 17 blast that killed 14 people and injured about 200.
Connealy has raised the possibility that authorities might never uncover the cause. A team of 80 investigators have conducted 300 interviews and are combing through an area that's about 15 acres. He compares the work to an archaeological dig.
The damage is estimated to be $100 million.
