This case is recorded on the grounds that it is of unusual interest, both from the legal and medico-scientific points of view; at the same time those interested in the “Psychology of Crime” may find food for thought. The illegitimate son of the deceased was found guilty of his non-capital murder. The immediate motive appeared to be the father's dislike of his son's homosexual associations; to this may be added the psychological insecurity of the accused, arising from his background, and a potential character change in the deceased, arising out of an accident (or a previous attempt at murder). Stress is laid on the ability of a Police Force, deficient in practical experience of the investigation of murder, to adhere to a prearranged plan, on the importance of team work—remembering that the onus of proof is on the prosecution—and on the fact that the proof may require time. Proof of innocence is as important as proof of guilt. Items of potential research are offered, to those who have the time and funds to pursue them, in the field of Finger Prints and Forensic Medicine.
