WACO - The head of a federal safety board says federal agents and the state fire marshal are blocking the board from investigating a deadly Central Texas fertilizer plant blast.
Rafael Moure-Eraso chairs the U.S. Chemical Safety Board. He has told a senator planning hearings into the West Fertilizer plant blast that the board's investigation of the blast has been blocked by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives and State Fire Marshal's Office.
The Waco Tribune-Herald reports that in a May 17 letter, he asks U.S. Sen. Barbara Boxer to help the board obtain evidence controlled by the ATF from the April 17 blast that killed 15 people and injured about 200 others.
