Federal prosecutors told a judge that a letter purportedly sent by Sam Bankman-Fried from prison was actually shipped via FedEx from somewhere else entirely, suggesting someone outside impersonated him.
The filing adds an unusual wrinkle to Bankman-Fried’s post-conviction fight. The FTX founder, sentenced to 25 years for fraud and conspiracy, has been pursuing a new trial from Federal Correctional Institution Terminal Island in San Pedro, California.
Prosecutors say the suspect letter was docketed March 16 but shipped from Palo Alto or Menlo Park, mislabeled the prison as a state facility, and carried a typed “/s/” instead of an actual signature.
Bureau of Prisons regulations bar inmates from sending mail through private carriers like FedEx, prosecutors noted.
Taken together, prosecutors said these discrepancies provide “reason to doubt” the letter was sent by Bankman-Fried.
The government did not accuse the defendant or his associates of fabricating the document, but the filing signals a willingness to challenge the reliability of materials submitted as part of his effort to secure a new trial.
Bankman-Fried has repeatedly argued that he did not receive a fair trial and has pointed to what he claims is new evidence, including the later recovery of customer funds through the FTX bankruptcy process.
Appellate judges have signaled skepticism toward that argument, stressing that the case turned on how customer funds were used and represented at the time, not whether creditors were later made whole.
