US prosecutors question authenticity of SBF letter from prison

U.S. federal prosecutors have raised doubts about the authenticity of a letter submitted by FTX founder Sam Bankman-Fried (SBF) from prison, suggesting it may have been sent from an external location via FedEx. According to CoinDesk, prosecutors informed a judge that the letter, filed on March 16, was sent from Palo Alto or Menlo Park, California, incorrectly identified the prison as a state facility, and contained a typed "/s/" instead of a signature. They argued that these discrepancies provide grounds to doubt the letter's origin, as federal inmates are prohibited from using private delivery services like FedEx. The outlet noted, however, that prosecutors have not directly accused SBF or his associates of forging the document. The challenge is seen as an effort to verify the credibility of materials submitted in the process of requesting a new trial.
