Hasan could receive the death penalty after he was convicted of killing 13 people during a mass shooting at Fort Hood in 2009.
At the beginning of Tuesday's hearing the judge reveled Monday's sentencing was cut short because the defendant had to deal with unforeseen "personal hygiene issues." Hasan has been paralyzed from the waist down since he was shot by police during his attack.
Tuesday's witnesses included the mother of Sergeant Amy Krueger and massacre survivor Lt. Col. Randy Royer.
Krueger’s mother told the jury her 29-year-old daughter joined the army after witnessing the events of September 11 on TV. She recalled having told her daughter she couldn't "take on Bin Laden all by yourself.”
To which her daughter replied, "Watch me."
Krueger was murdered along with 12 others in the Nov. 5, 2009, rampage. On Friday a jury of 13 officers convicted Hassan of 13 counts of premeditated murder and 32 counts of attempted premeditated murder for his actions.
Royer, who survived the shooting, took the stand with the help of a cane and said he can't be around large groups of people of go anywhere that has rows of chairs because they remind him of the crowded deployment where Hassan opened fire.
Royer was shot twice and suffered from several disabling injuries including Post Traumatic Stress Disorder.
Prosecutors expect to call their last witness soon and then Hassan, who chose to represent himself, will have the chance to either plead the jury for life in prison or remain silent and possibly receive a death penalty sentence.
