title: Homicide offenders 32 years later - a Swedish population-based study on recidivism.
abstract: BACKGROUND
  The literature on recidivism by homicide offenders is scarce despite its importance for individuals and for society.
  
  
  OBJECTIVE
  To establish the rate of seriously violent re-offending among homicide offenders and identify risk factors for such recidivism.
  
  
  METHODS
  A 1970s incident cohort of all homicide offenders, sane and insane, from two regions of Sweden (N = 153) was followed up until 2007 using data from the national crime register.
  
  
  RESULTS
  Ten per cent of the cohort (n = 15) re-offended. The mean time from index offence to recidivism was 9.4 years. Five people (3%) committed a further homicide, and it was established that another five (3%) offenders had killed before the index offence. Prospective risk factors for violent recidivism were young age, psychotic disorder, male victim, acquainted victim and intoxicated victim.
  
  
  CONCLUSIONS
  The prevalence of repeated homicide is higher than previously reported. Victim variables and mental disorder in conjunction with substance abuse appear to be two domains of particular significance for recidivism.
