Latest available data relate to offences currently recorded as homicides and were published in “Violent Crime Overview, Homicide and Gun Crime 2004/05” (HOSB 02/06). As of 28 November 2005, there were 820 offences currently recorded as homicide in England and Wales during the financial year 2004-05. In 30 of these cases the apparent circumstance of the offence was classed as being an
“irrational act carried out by an apparently insane or disturbed subject”
included in the above publication as “suspect mentally disturbed”. However, as only one circumstance can be recorded per case, these figures do not include all those homicides committed by a suspect with mental health problems. Full data for 2005-06 are scheduled to be published in late January 2007.
The Home Office also publishes annual criminal statistics and data about persons managed under Mental Health Act powers, including those convicted of homicide. In 2004, 626 persons were convicted of homicide (“Criminal Statistics 2004”, HOSB 19/05). Ninety-nine persons convicted of homicide were detained under part III of the Mental Health Act 1983 (“Statistics of Mentally Disordered Offenders 2004”, HOSB 22/05).
