FORT HOOD, Texas (AP) — The opening week of the trial for an Army psychiatrist accused in the 2009 shooting rampage at Fort Hood is ending with graphic and emotional testimony from survivors.

Army Maj. Nidal Hasan on Friday will continue defending himself against charges of killing 13 people and wounding more than 30 others. His standby attorneys insist that Hasan is trying to secure a death sentence, but a military judge says Hasan has the right to choose his legal strategy.

Spc. Meagan Martinez on Thursday was among more than a dozen witnesses who recalled Hasan relentlessly firing into a room of soldiers waiting to receive medical clearance for deployment.

Martinez said Hasan fired with a "cold, calculated, hard stare." She said the rampage felt like an eternity.

Hasan is not questioning most witnesses.
