The 18-count indictment alleges the defendants used real and counterfeit mailbox keys to steal mail and use victims’ personal information to create fake identities and drain victims’ accounts, according to a press release from U.S. Attorney for the Northern District of California David Anderson.

The crimes were alleged to have occurred between January 2018 and August 2019.

According to the indictment, the defendants raided apartment building mailboxes throughout the South Bay, including in Sunnyvale, Palo Alto, Santa Clara, Redwood City, Menlo Park, and San Jose. After stealing mail in bulk from apartment buildings, the defendants obtained personal identifying information, such as names, addresses, telephone numbers, and dates of birth, from the stolen mail and used it to create counterfeit driver licenses in the names of the victims, the complaint said.
