A schizophrenic boy (age not given, but over sixteen) took part in a brutal holdup and robbery at the behest of older men to whom he was homosexually attached, his main sexual propensity being fellatio. His criminal tendencies were originally directed toward his rigid, overdisciplining father. The case, naturally not available for psychoanalysis, was studied with the help of Murray's test series for thematic apperception and a series of the patient's drawings which illustrate his unconscious. Fellation appeared to be related to oral restitution fantasies expressed in sadistic assaults carried out on levels of urethral aggression. The solution of the Oedipal conflict was attempted via inversion, sadism and identification with the enemy, and was symptomatized in stealing, fantasies and threats of killing and fellatio. Of basic importance was the unconscious equation: phallus=nipple=gun.
