Paper offers tentative clinical inferers into adolescent murder based on a study of a group of 8 murderers aged 14-20. 3 cases are presented in detail. These patients suffered from early experiences of deprivation. This results in an underdeveloped ego & a vulnerability to violent outburts. Theory is presented that the act of murder for these adolescents is characteristic of a type of ego failure. Suggestions are offered for a treatment approach based on these apparent ego limitations.
