FORT HOOD, Texas — The Army psychiatrist who fatally shot 13 people at Fort Hood decided not to present any evidence during his trial’s penalty phase on Tuesday even though jurors are deciding whether to sentence him to death.
Major Nidal Hasan rested his case without submitting any evidence to counter the testimony from victims’ relatives, which prosecutors hope will persuade jurors to hand up a rare military death sentence. The same jury convicted Hasan last week for the attack, which also wounded more than 30 people at the Texas base.
The judge dismissed jurors after Hasan declined to put up a defense. But she then asked Hasan more than two dozen questions in rapid fire, affirming that he knew what he was doing. His answers were succinct and just as rapid.
‘‘It is my personal decision,’’ he said. ‘‘It is free and voluntary.’’
The judge, Colonel Tara Osborn, then read him several court opinions to back up her decision not to introduce evidence in Hasan’s favor on her own.
‘‘In other words, Major Hasan, you are the captain of your own ship,’’ Osborn said.
Closing arguments are scheduled for Wednesday. Whether jurors will hear from Hasan remains unclear. He has been acting as his own attorney but has put up nearly no defense since his trial began three weeks ago.
The trial’s penalty phase, however, is Hasan’s last chance to tell jurors what he’s spent the last four years telling the military, judges, and journalists: that he believes the killing of unarmed American soldiers preparing to deploy to Iraq and Afghanistan was necessary to protect Muslim insurgents. He was barred ahead of trial of making such a defense.
Hasan rested his case shortly after more than a dozen relatives of those killed testified about their lives since the attack.
Sheryll Pearson sobbed when shown a photo of her son, Private First Class Michael Pearson, hugging her during his graduation.
‘‘We always wanted to see who he was going to become. Now that was taken away from us,’’ she said.
Teena Nemelka lost the youngest of her four children, Private First Class Aaron Nemelka, whom she called, ‘‘my baby.’’ She talked about her frantic searches for information in the moments after learning about the Nov. 5, 2009, shooting and about her fear of hearing a knock at the front door of her home.
‘‘You just freeze,’’ she said. ‘‘You don’t want to open that door.’’
But the knock came, with ‘‘the worst news you could ever hear.’’
Joleen Cahill told jurors that she misses hearing her husband’s footsteps in their Texas home, which she said now feels empty. Witnesses have said her husband, Michael Cahill, was armed only with a chair when he tried to charge Hasan as Hasan opened fire on unarmed soldiers inside a crowded medical building at Fort Hood.
The 62-year-old physician’s assistant was the only civilian killed in the attack.
‘‘One of the hardest things was being alone for first time in 60 years of my life. No one to come home to at night. No conversation. We loved to talk politics,’’ she said.
Philip Warman said the slaying of his wife, Lieutenant Colonel Juanita Warman, ‘‘was like I had something ripped out of me.’’
‘‘I pretty much drank until the following June,’’ he said.
He said he checked into a substance abuse center for 28 days, and he had friends remove his weapons from his home because he didn’t trust himself.
Warman now takes the coins distributed during his Alcoholics Anonymous meetings to Arlington National Cemetery, where his wife is buried next to another Fort Hood victim, Major Eduardo Caraveo.
‘‘I push them into the ground at my wife’s grave,’’ he said.
One of the soldiers who survived the shooting walked into the courtroom Tuesday with the help of a cane. Lieutenant Colonel Randy Royer, who underwent multiple surgeries after being shot in the arm and leg, told jurors that he also suffered from post-traumatic stress disorder.
Prosecutors want Hasan to join just five other US service members currently on military death row. That would require a unanimous decision by the jury of 13 military officers.
No American soldier has been executed since 1961.
