(WXII) Three men are facing felony conspiracy charges after their plan to blow up North Carolina's Alamance County Detention Center was foiled because a letter and drawings describing the alleged plot was sent to the wrong address.
"This is a very, very serious case," Alamance County Sheriff Terry Johnson said.
The Alamance County Sheriff's Office said Sean Castornia, 43, of Graham, was the "mastermind" of the plan and conspired with Shannon Gurkin, 23, of Graham, and Dakota Marek, 24, of Burlington, to develop a bomb while they were in custody together at the jail at one point in time.
"Mr. Castorina, while in the Alamance County Jail with two other inmates, solicited them to assist in building a bomb with his directions and planting the bomb and setting it off at the Alamance County Detention Center south wall," Johnson said.
After Gurkin and Marek were released from jail, Castorina, who remained in custody on first-degree murder charges related to the death of 84-year-old Harold Simpson, allegedly sent letters and made phone calls to them about how to build a bomb, where to get supplies and where to plant it.
