CONWAY, S.C. (WBTW) — A Conway teen is facing a terrorism charge after authorities said he spent months working to join ISIS and obtained instructions on how to build a weapon of mass destruction, authorities said Wednesday.

Daniel Fox Fischer, 17, was arrested June 9 by the South Carolina Law Enforcement Division on one count each of threatening or conspiring to threaten real or personal property using a destructive device and possession or using a weapon of mass destruction for an act of terrorism.

Fischer was booked into the J. Reuben Long Detention Center’s juvenile facility, and his case will be prosecuted by the 15th Circuit Solicitor’s Office.

According to a SLED warrant, Fischer “communicated his intent to join a foreign terrorist organization” later identified as ISIS between April and August of last year.

“Defendant took proactive steps with others to obtain the technical expertise to carry out an attack,” warrants say.

An investigation by the FBI’s Joint Terrorism Task Force found that Fischer obtained instructional videos and instructions for “making an explosive device, information about (improvised explosive devices) and recipes for making explosive material C4.”

Authorities also recovered training manuals and electronic communications “supporting terrorism activities,” including Fischer showing support for ISIS while wearing an explosive vest.

A confidential source and other records “indicated intent to use a destructive device against targets within the state,” warrants say.
