Jury Subpoenas Drivers’ Records in Ricin Inquiry

A federal grand jury has subpoenaed work records for nine truck drivers employed by a Little Rock, Ark., company that transports mail for the U.S. Postal Service, as part of an effort to determine who might have delivered the first ricin-packed letter last year to a South Carolina postal processing center.

Officials of Mail Contractors of America Inc. said a subpoena sought driver logs, time sheets, cellphone and telephone records and delivery receipts and expenses, the Washington Post reported. Eight of the truckers made deliveries to the facility. The other driver was a former employee.
