Authorities in eastern Iowa believe a man’s death may be linked to chemicals used to make methamphetamine. 37-year old Mike Stealy was found dead on the back steps of his home in Dewar Wednesday. Officials say it appears Stealy may have been dead for some time. Black Hawk County deputies found a gas tank that had been altered to transport anhydrous ammonia, a key chemical used in making meth, in his pickup. A hazardous materials team also found high readings of ether and ammonia around Stealy’s house. An autopsy is being conducted to determine if the chemicals indeed caused the man’s death.
