Two separate homegrown terror cases ended with guilty pleas this week. Colorado resident Jamie Paulin-Ramirez pled guilty Tuesday to providing "material support" to a terrorist by marrying him; Awais Younis, a 25-year-old who threatened to blow up the DC Metro system and place a bomb under a Georgetown sewer head during rush hour, was expected to change his plea to guilty Wednesday.

Paulin-Ramirez traveled to Ireland in September 2009 at the invitation of Colleen LaRose, aka "Jihad Jane", to attend a training camp for terrorists. The same day she arrived, she married an Algerian terrorism suspect planning to train with the Algeria-based al-Qaida in the Islamic Maghrib and recruit for Pakistan's terror-linked Inter-Services Intelligence (ISI).

The crime of material support "can be as basic as supplying emotional support and comfort," according to Jeremy Ibrahim, Paulin-Ramirez's lawyer. Her marriage, which her lawyer said was "for the love of Islam, not for the love of her husband," was part of the group's plan to participate in terrorist training and attacks.

"Today's guilty plea by Jamie Ramirez, coupled with that of Colleen LaRose last month, underscores the evolving nature of the terrorist threat we face," said acting Assistant Attorney General Hinnen.

Younis is expected to plead guilty plea to a charge of "threatening interstate communications." The allegations stemmed from several online rants threatening the DC Metro system and other targets, in which Younis described how to build a pipe bomb and targeted the third and fifth cars of a Metro train because they "had the highest number of commuters." $22,000, large quantities of drugs, and a loaded hand gun were also found hidden in his home, according to prosecutors.
