“…The rates of homicide-suicide vary considerably between different countries; the perpetrators of such events are likely to be older than perpetrators of homicide-only cases, and the victims are often female intimate partners (either former or current) (Liem, Barber, Markwalder, Killias, & Nieuwbeerta, 2011;Panczak et al, 2013). In Sweden, a declining incidence of homicide-suicides has been reported for the period 1991-2010 (Regoeczi, Granath, Issa, Gilson, & Sturup, 2016). Since homicide-suicide offenders cannot be interrogated post offense, the circumstances that precede such tragic events are sometimes difficult to disentangle, and police investigators and researchers may have to rely on notes left behind by the perpetrator as the only source of information (Sturup & Caman, 2015;Weeke & Oberwittler, 2017).…”
