Mr. Shahzad apparently went back and forth to Pakistan often, returning most recently in February after what he said was five months visiting his family, prosecutors said.
A Pakistani intelligence official who spoke on condition of anonymity said Mr. Shahzad had traveled with three passports, two from Pakistan and one from the United States; he last secured a Pakistani passport in 2000, describing his nationality as “Kashmiri.”
