The FBI has charged a 26-year-old Missouri man with terrorism after agents say he attempted to derail an Amtrak train in Nebraska by triggering the trains emergency brakes.

Taylor M. Wilson of St. Charles, Missouri, had previously traveled with members of a neo-Nazi group to the white nationalist rally in Charlottesville, Virginia, and expressed an interest in killing black people, according to court documents unsealed Wednesday.

After Wilson was arrested for triggering the trains brakes in October, FBI agents found weapons, tactical gear and white supremacist documents at his home. Some items were in a hidden compartment behind a refrigerator, according to the court documents.

FBI Special Agent Monte Czaplewski said that Wilson, who has a concealed carry permit, boarded the train intending to carry out a terrorist attack and pulled the emergency brake with intent to harm those aboard on Oct. 22, according to the affidavit.

Czaplewski also said he believed Wilsons firearms have been used for or obtained in anticipation of engaging in or planning to engage in criminal offenses against the United States.

There were about 175 people aboard the train from California to Missouri when Wilson triggered the brakes, The Associated Press reported in October.
