The suspect in the Fort Hood shooting, Army Major Nidal Hasan, has roots in the Washington area.
Hasan was born in Arlington, Virginia and studied at Virginia Tech. He received his medical degree from the military's Uniformed Services University in Bethesda. For six years before reporting for duty at Fort Hood, the 39-year-old Army major worked in psychiatry at the Walter Reed Army Medical Center.
He also attended a local mosque, the Muslim Community Center in Silver Spring, Maryland. Imam Faizul Khan says he knew Hasan for more than 10 years. Khan says they mostly discussed religion and says Hasan was quiet, reserved and never seemed controversial.
Muslim groups say they've received threatening phone calls and e-mails in the wake of the shootings and are urging calm, saying this was the act of one man.
