Court records say a state Department of Justice agent found an "explosives laboratory" and white supremacist literature while investigating a fatal explosion at a Wisconsin apartment building.
State investigator Kevin Heimerl says he found 13 jars of the explosive triacetone triperoxide, or TATP, in the Beaver Dam home, along with bomb-making instructions. WKOW-TV reports Heimerl says containers labeled TATP were also found in an apartment garage.
The explosion last month killed 28-year-old Benjamin Morrow, who lived in the apartment. Authorities say they also found white supremacist literature in the bedroom. It is not clear if Morrow identified as a white supremacist.
TATP can explode if subjected to heat, friction, static electricity or shock. Authorities were forced to burn down the apartment building because the chemicals were too volatile to remove.
