The 32-year-old doctor was charged with being an accomplice to the assassination, though it was proven he had no previous relationship with the assassin. A military ourt tried him and sentenced him to life imprisonment in the horrible federal prison on Shark Island off the coast of Florida.
Mudd never stopped practicing medicine despite his imprisonment. During an epidemic of yellow fever in the prison, he worked arond the clock saving the livles of hundreds of prisoners and guards alike.
So impressive were his actions that he was officially pardoned by President Andrew Johnson in 1869 and given his freedom. Mudd returned to Maryland and tried to resume his medical practice, but his life was essentially ruined.
