Google "Lee Harvey Oswald wife beater" and you will come away with ample sources of it. After his death, Oswalds life was gone though like none other. Countless interviews with former neighbors and family shows Oswald to be a bully, a wife beater as well as a loving father. One may disagree as to Oswald being the lone gunman, but there is no disagreement that he used Marina as a punching bag. There is evidence that suggests that Oswald was emotionally unbalanced and acted against JFK at least partly because of this factor. Oswald was diagnosed with ""personality pattern disturbance with schizoid features and passive - aggressive tendencies" at the age of thirteen. The fact that Oswald physically and verbally abused his wife Marina adds to this picture of instability.
There does appear in the research that Oswald may have had "handlers", but no one ever seriously thought Marina was one.
