Documents say grand jury widens Warren-related probe

Documents indicate that a federal grand jury has widened an investigation related to city operations in the Detroit suburb of Warren. The Macomb Daily of Mount Clemens reported documents it obtained under the Freedom of Information Act outlined details of a Sept. 25 subpoena, including employment information, records related to contracts and other materials. The subpoena doesn't explain why investigators are seeking the records. Last month, the city's mayor said a federal grand jury wanted records about Warren's trash trucks. An earlier subpoena from the grand jury seeks documents about the purchase of trash trucks and records that explain the relationship between Warren and a company that runs Detroit's trash incinerator.
