A device made of materials like those used in the 1995 Oklahoma City bombing could have been a former student’s “dry run” to see how authorities would respond to a bomb threat at Trident Technical College, Sheriff Al Cannon said Friday.
Local investigators and federal terrorism experts wouldn’t say whether the device could have exploded and caused damage near the North Charleston campus’ Student Center, which was mostly abandoned Monday for the holiday break.
The device contained ammonium nitrate, the same, readily available fertilizer that Timothy McVeigh used in his attack on the Oklahoma City federal building that killed 168 people.
