Circumstantial evidence
The U.S. Marshals Service case file remains open and active, however. Morris and the Anglin brothers remain on its wanted list. Circumstantial evidence uncovered in the early-2010s seemed to suggest that the men had survived, and that contrary to the official FBI report of the escapee's raft never being recovered and no car thefts being reported, a raft was discovered on nearby Angel Island with footprints leading away, and a car had been stolen on the night of the escape by three men, who could have been Morris and the Anglins, and that officials then engaged in a cover-up. Relatives of the Anglin brothers presented further circumstantial evidence in the mid-2010s in support of a longstanding rumor that the Anglin brothers had fled to Brazil following the escape; a facial recognition analyst concluded that the one piece of physical evidence, a 1975 photograph of two men alleged to be John and Clarence Anglin, did support that conclusion.
