A Waxahachie man was arrested on Tuesday after a traffic stop revealed that the man's car was loaded with bomb-making supplies.
A Waxahachie, Texas, man was arrested in Dallas on Tuesday after bomb-making supplies were found in his car during a traffic stop.
Clayton Todd Earthman, 24, told federal agents he is a "Doomsday prepper."
"Doomsday Preppers" is a reality TV show on the National Geographic Channel that details the lives of people who are heavily armed in preparation for major natural disasters or national conflicts. Earthman is not listed as a participant in the TV show on the National Geographic Channel website.
Earthman was pulled over Tuesday afternoon after running a stop sign at the corner of Hilltop Street and Lovett Avenue in East Dallas, according to a federal complaint.
The complaint said police officers saw a Glock .357 pistol in plain view on the floor of Earthman's car.
Officers ordered him out of the vehicle, right in front of Maria Macedo's home.
Her grandson, Jonathan Macedo, said she has seen other police activity in the neighborhood but noticed the large number of officers at this arrest.
"Anybody can stop them, but she was scared about this," he said.
Witnesses said agents from the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives arrived with a large van to seize items from Earthman's car.
Juanita Holgin said she watched from her front porch.
"And they had all the doors and hood and stuff open, [and] they were taking all kinds of stuff out of the car," she said.
According to an ATF complaint against Earthman, agents found "large amounts of chemicals, supplies and literature suspected to be for bomb making purposes" and "handwritten notes describing now to build various explosive devices and booby traps."
The complaint said Earthman told the agents he had "used methamphetamine approximately three days prior."
Records show Earthman has a 2008 conviction for marijuana possession. The complaint said Earthman told the agents he is using methadone to quit using heroin, which he used for about a year.
According to the complaint, Earthman allowed agents to search his Waxahachie home, where they found more guns and explosive evidence.
The home is many miles away from the East Dallas Street where Earthman was arrested.
"I take care of my grandkids here," Holgin said. "There are a lot of kids here. This is just a family-oriented neighborhood, so I have no idea what he would be doing here."
ATF representatives did not respond to requests for additional information about the case and a Dallas police representative could find no Dallas police reports on the arrest.
