CBN News is learning more about the man behind the shooting rampage at Fort Hood, Texas. And some of the new information is disturbing.
An Army psychologist, Major Nidal Malik Hasan, was trained to help solders in distress, but he had been on the radar of law enforcement officials for months.
Click play to watch the CBN News report followed by analysis from CBN News Terrorism Analyst Erick Stakelbeck and reporter Wendy Griffith, who's at Fort Hood following the story.
Thursday's shooting has raised questions about Hasan's past and whether red flags about him were ignored. Col. John Folsom -- a Marine with 29 years of service -- spoke with CBN News about this. Click here for his comments.
In an Internet posting, at least six months ago, Hasan compared suicide bombers to GI's who save other troops by throwing themselves on a grenade.
Hasan apparently carried out the attacks on his own, but the possibility that he was acting on behalf of some radical group has not been ruled out.

"It's one of those things that he obviously went to kill a lot of people and commit suicide. Maybe in his own mind that he's saving future lives," former FBI agent Brad Garrett said.
The 39-year-old was scheduled to be deployed overseas later this month, but his family says he had hired a lawyer to get out of it.
On surveillance video obtained by CNN from a 7-11 store near Fort Hood, Hasan is seen wearing traditional Muslim garb, just hours before the shootings.
Hasan was reportedly going to work with Muslims in the U.S. military.
"He was going to be kind of the caretaker for Muslim soldiers. Sometimes Muslim soldiers have a rift between what they're doing and their faith," said Major Khalid Shabazz, an Army Muslim chaplain. "That person who is a leader needs to quell some of those fears and help them through that process."
Hasan reportedly hoped President Barack Obama would pull troops out of Iraq and Afghanistan and argued with his military colleagues who support the wars.
Before arriving at Fort Hood, Hasan worked at Walter Reed Army Medical Center for six years as a intern, resident and fellow in disaster and preventative psychiatry.
There, he reportedly received a poor performance evaluation and, as an intern, had some "difficulties" with patients that required extra counseling and supervision.
His cousin told Fox News he believes Hasan was fed up with being teased about his heritage.
"It was the harassment that I think was what got to him," Nader Hasan told Fox News. "Him being referenced from his Middle Eastern ethnicity, even though he was born and raised here and went to high school here in northern Virginia."
Federal law enforcement agents are searching Hasan's home, looking for clues as to what led the soldier to allegedly kill his comrades.
A ceremony to honor the dead is being planned at the Dover, Delaware Air Base where the bodies will be taken for forensic testing.
