A lead conspirator in a plot to attack a U.S. military facility in Seattle pleaded guilty Friday to terrorism and firearms related charges. Abu Khalid Abdul-Latif (aka Joseph Anthony Davis) and Walli Mujahidh (aka Fredrick Domigue Jr.) of Los Angeles were arrested and charged in June 2011 with planning an assault on the Seattle Military Entrance Processing Center (MEPS) using grenades and machine guns.

The center recruits prospective candidates to the U.S. military. The MEPS building houses several civilian and military employees and also includes a federal daycare center.

Mujahidh pleaded guilty last December. Another individual recruited by Abdul-Latif to aid in the attack reported the plot to the FBI and became a paid informant. The informant promised to provide weapons for the attack. The three machine guns he subsequently supplied to the defendants were rendered inert by agents investigating the attack, the complaint said.

The plot was inspired by the November 2009 Fort Hood massacre carried out by Army psychiatrist Nidal Hassan that killed 13 people and wounded 30 others. The co-conspirators condemned U.S. military actions in Afghanistan, Iraq, and Yemen. In secretly-recorded conversations, Abdul-Latif criticized the U.S. military for "invading our lands…stealing our resources…locking up our brothers and sisters, you're raping our sisters in Guantanamo Bay…you're in Islamic countries and even when you're asked to leave, you won't leave…"

"This defendant plotted to kill American servicemen and women and other innocent people in furtherance of his extremist views," U.S. Attorney Jenny A. Durkan said in a press release announcing the guilty plea. "The continued vigilance of the community and the work of law enforcement ensured that we were able to successfully disrupt his deadly plan and bring Mr. Abdul-Latif to justice."

If the plea agreement is accepted by the court, Abdul-Latif will receive a sentence between 17 and 19 years in prison at his sentencing hearing scheduled for March 25.
