Military officials say the suspected shooter at Fort Hood was a psychiatrist at Walter Reed Army Medical Center for six years before being transferred to the Texas base in July.
The officials had access to Maj. Malik Nadal Hasan's military record. They said he received a poor performance evaluation while at Walter Reed.
The officials spoke on condition of anonymity because military records are confidential.
Federal law enforcement officials say the Hasan came to their attention at least six months ago because of Internet postings that discussed suicide bombings and other threats.
The Virginia-born soldier was single with no children. He was 39 years old.
He is a graduate of Virginia Tech University, where he was a member of the ROTC and earned a bachelor's degree in biochemistry in 1997. He received his medical degree from the military's Uniformed Services University of the Health Sciences in Bethesda, Md., in 2001. At Walter Reed, he did his internship, residency and a fellowship.
