A third North Carolina man admitted Wednesday to aiding others in a plot to wage jihad abroad.

Dylan Boyd, 24, pleaded guilty to one count of aiding and abetting a conspiracy to provide material support to terrorists.

Boyd's plea deal follows pleas by his brother and father. His father and the ringleader of a North Carolina terror cell, Daniel Patrick Boyd, pleaded guilty Feb. 9 to one count of conspiring to murder, kidnap and maim individuals in a foreign country in addition to one count of material support.

Dylan's younger brother, Zakariya a.k.a. "Zak," in June pleaded guilty to one count of conspiracy to provide material support to terrorists.

From 2006 through 2009, prosecutors say that the Boyds conspired with others to provide currency, training, transportation and personnel to terrorists.

Daniel Boyd was recorded by the FBI preaching violence to his sons. "The blood of Muslims has become cheap…because most of the Muslims have abandoned jihad," Boyd told Dylan and Zak.

Another defendant in the case, Jude Kenan Mohammed, remains at large and is believed to be in Pakistan. The Wall Street Journal on the tenth anniversary of the 9/11 attacks identified Mohammed as a leader U.S. officials believe to be a particular threat because he used to live in the U.S.

A trial for the remaining co-defendants is scheduled to begin next week in New Bern, N.C.

Dylan Boyd faces 15 years in prison at sentencing.
