Maj. Malik Nadal Hasan was an Army mental health professional, a psychiatrist or a psychologist, who had been promoted to major in May.
A neighbor said an Army psychiatrist suspected of opening fire on fellow soldiers at Fort Hood, Texas cleaned out his apartment in the days before the rampage that left 13 dead and 30 injured.
Neighbor Patricia Villa said Maj. Nidal Malik Hasan came over to her apartment on Wednesday morning and told her he was going to be deployed on Friday.
She said he gave her some frozen broccoli, some spinach, T-shirts, shelves and a new Quran, the Muslim holy book. She said he returned on Thursday morning and gave her his air mattress, several briefcases and a desk lamp.
Villa said Hasan then offered her $60 to clean his apartment Friday morning after he supposedly was to leave.
Authorities said Hasan on Thursday went on a shooting rampage at Fort Hood that left 13 people dead.
