Gate News reports that on March 23, U.S. federal prosecutors submitted documents to a judge questioning the authenticity of an appeal letter sent from prison by FTX founder Sam Bankman-Fried (SBF). Prosecutors pointed out that the letter was actually sent via FedEx from the Palo Alto or Menlo Park area, which does not match the location of SBF’s federal prison at Terminal Island. Additionally, the letter incorrectly listed its location as a state facility and used a typed signature instead of a handwritten one, violating federal prison regulations that prohibit the use of private couriers for mailing. While prosecutors did not directly accuse SBF or his associates of forging documents, they stated that these discrepancies are sufficient to raise reasonable doubts about the letter’s origin and could impact the credibility of evidence in his reexamination request. SBF is currently serving a 25-year sentence for fraud and conspiracy and is actively seeking a retrial, but the appellate judges have shown clear skepticism toward his claims.
