WACO, Texas - An AWOL soldier accused of plotting to launch an attack on Fort Hood was defiant during his first court appearance on Friday, yelling out the name of the Army psychiatrist blamed in the 2009 deadly shooting rampage at the same Texas base.
Federal prosecutors charged 21-year-old Pfc. Naser Abdo with possessing a destructive device, two days after he was arrested at a motel about 3 miles from the front gate of Fort Hood. He told authorities he planned to construct two bombs in the motel room using gunpowder and shrapnel packed into pressure cookers and then detonate the explosives at a restaurant frequented by soldiers, court documents released Friday said.
Abdo, who had requested conscientious objector status because his Muslim beliefs prevented him from fighting in Iraq and Afghanistan, refused to stand up during Friday's hearing when everyone in the court was asked to rise for the judge.
As he was being led out of the courtroom, he yelled out "Iraq 2006" and the name of the 14-year-old Iraqi girl who was raped and murdered in 2006 by a U.S. soldier. He then shouted: "Nidal Hasan Fort Hood 2009."
Hasan, an Army major and psychiatrist, is charged in the 2009 deaths of 13 people at Fort Hood in the worst mass shooting ever on a U.S. military installation.
Abdo's words in court were a sharp contrast to an essay he wrote last year as the first anniversary of the Fort Hood shootings approached and as he petitioned for conscientious objector status. In the essay, obtained by The Associated Press, Abdo said the attacks ran against his beliefs as a Muslim and were "an act of aggression by a man and not by Islam."
Abdo was approved as a conscientious objector this year, but that status was put on hold after he was charged with possessing child pornography. He went absent without leave from Fort Campbell, Ky., during the July 4 weekend.
On July 3, Abdo tried to buy a gun at a store near Fort Campbell, according to the company that owns the store. Police in Killeen, where Fort Hood is located, said their break in the case came Tuesday from Guns Galore LLC the same gun store where Hasan bought a pistol used in the 2009 attack. Store clerk Greg Ebert said Abdo arrived by taxi and bought 6 pounds of smokeless gunpowder, three boxes of shotgun ammunition and a magazine for a semi-automatic pistol.
"We would probably be here today, giving you a different briefing, had he not been stopped," said Killeen Police Chief Dennis Baldwin, who called the plan "a terror plot."
Authorities said they found two clocks, spools of auto wire, a Winchester .40 caliber ammunition and a handgun in a backpack, according to court documents. They also discovered an article titled "Make a bomb in the kitchen of your Mom," the same title of a how-to article featured in Inspire, the English-language magazine by the terror group based in Yemen, al Qaeda in the Arabian Peninsula.
It was not immediately known if Abdo had any connections to terror groups or Hasan. He was ordered held without bond, and his court-appointed attorney did not plan to comment Friday.
James Branum, an Oklahoma attorney who had been representing Abdo on the child pornography charges, said Friday he had not heard from Abdo.
He said Abdo was "stressed and anxious" about the child pornography charges but "I didn't see any indication he would do anything like this. ... I would not have taken the case if I had any indication of this kind of mindset."
Several writings by Abdo obtained by the AP portray a devout infantry soldier struggling with his faith while facing the prospect of deployment and what he felt was the scorn of his peers.
"Overall, as a Muslim I feel that I will not be able to carry out my military duties due to my conscientious objection," Abdo wrote in his application for conscientious objector status. "Therefore, unless I separate myself from the military, I would potentially be putting the soldiers I work with in jeopardy.
FBI, police and military officials have said little about whether or how they were tracking Abdo since he left Fort Campbell. Patrick J. Connor, special agent in charge with Army Criminal Investigation Command at Fort Hood, said efforts had been made to locate him after an arrest warrant was issued but he would not elaborate.
Abdo grew up in Garland, a Dallas suburb about 170 miles from Fort Hood. In his essay, which he sent to the AP last year as he made his conscientious-objector plea, he said his mother is Christian and his father is Muslim, and that he decided to follow Islam when he was 17.
