Abstract

Psychiatric research into violent offences, particularly murder, have been scant in the South East Asian region, with the last major review of homicides in Singapore and their association with psychiatric disorders being as far back as 1985. This study seeks to update the psychiatric community on individuals charged with murder in Singapore from 1997 to 2001 and particularly to further investigate the phenomenon of 'migration psychosis' in relation to foreigners in this sample who have committed homicide. One hundred and ten individuals in Singapore were charged with murder between 1997 and 2001. Socio-demographic data, psychiatric diagnoses, offence and victim profiles and court outcomes were obtained. The group consisting of offenders who were Singapore citizens or permanent residents was compared with those offenders who were foreigners. Analysis was done using the statistical package, SPSS. The proportion of foreigners in this study who committed homicide is significantly higher than the proportion of citizens/permanent residents in the general population. Foreigners who commit homicide also appear to (i) suffer from the more serious psychiatric illnesses of mood and psychotic disorders compared with locals, (ii) be less likely to have a known history of violence or a past forensic history and (iii) be more likely to be new to psychiatric services compared with the local homicide offenders. Compared with locals, foreigners appear to have a higher risk for committing homicide. Yet, they are less likely to appear early enough before mental health services. Some form of basic education to employers of foreigners as well as to the foreigners themselves on the early signs of mental illness is recommended.
