(ABC News Radio) The army psychologist on trial for killing 13 people in a 2009 shooting rampage rested his case Wednesday in a matter of seconds, calling no witnesses and putting on no defense.

Prosecutors on Tuesday wrapped a weeks-long case against Maj. Nidal Hasan, calling many of the 30 people whom he wounded in a shooting spree at Ft. Hood in Texas.

Hasan, who is acting as his own lawyer and is on trial for his life, has never denied entering the Soldier Readiness Processing Center, a busy building where unarmed soldiers were getting ready for upcoming deployments to Afghanistan, and shouting “Allahu akbar,” Arabic for “God is great,” before opening fire.

When asked by judge Col. Tara Osborn how he wished to proceed, Hasan simply answered: “the defense rests.”
