Brian Kim, a data analytics and forensics expert, may speak to internal messaging between Bankman-Fried and his employees at FTX and its sister companies. If he is called to the stand, he may testify on “the content, metadata, and file paths associated with Slack data and Google documents,” that allegedly prove Bankman-Fried instructed his employees to destroy evidence of his companies’ alleged fraud. That data would include “the fields [of documents and messages] listing the author, custodian(s), and viewer(s), as well as the content created, modified, viewed, saved, and/or deleted dates,” court filings show. Like Bishop, if he is called to testify, his focus would be on rebutting DOJ testimony.
