The story of how Hillary's "personal" emails came to be deleted using, the now infamous, BleachBit is quite the tale. Below we attempt to piece together how the story unfolded per the recent FBI disclosures.
Hillary resigned from the State Department in February 2013. Shortly thereafter, in "spring 2013", Hillary's close aide, Monica Hanley, worked with Bill Clinton's aide, Justin Cooper, to archive all of Hillary's emails from the "Pagliano Server" that Clinton used to house her State Department emails while serving as Secretary of State. With Cooper's assistance, Hanley was successful transferring all of Hillary's emails from the "Pagliano Server" to an Apple MacBook with a duplicate copy saved to a "Thumb Drive".
At that point, Hanley "forgot" to provide the archived emails to Clinton's staff. So apparently the Apple MacBook and Thumb Drive just stayed around Hanley's house for a year.
Then in February 2014, Hanley decided it wasn't the best idea to leave the email records of the former U.S. Secretary of State in her sock drawer forever. As such, she decided it was time to backup the archived emails to Clinton's new server hosted by Platte River Networks (PRN) in Denver, Colorado.
Unfortunately, she was not successful with the remote backup and mailed the computer to an Undisclosed PRN Staffmember to help with the task.
Apparently, the Undisclosed PRN Staffmember also had difficulty uploading the emails to the new PRN server because the "Apple MacMail" format was incompatible with Microsoft Exchange. So, he/she came up with a workaround that involved transferring all of Clinton's emails to a new gmail account and then exporting them to the PRN server.
