The motivational dynamics and legal issues involved in the killings of mothers by juvenile and adult offenders have been addressed by scholars and mental health professionals in many clinical reports and studies (see, e.g., Clark, 1993;Dogan, Demirci, Deniz, & Erkol, 2010;Ewing, 1997;Green, 1981;Heide, 1992Heide, , 2013Heide & Frei, 2010;Heide & Solomon, 2009;Holcomb, 2000;Lauerma, Voutilainen, & Tuominen, 2010;Liettu, Säävälä, Hakko, Räsänen, & Joukamaa, 2009;Mack, Scherl, & Macht, 1973;Russell, 1984;Scherl & Mack, 1966;Schlesinger, 1999;Schug, 2011;Singhal & Dutta, 1992;Wertham, 1941;Wick, Mitchell, Gilbert, & Byard, 2008). In sharp contrast, virtually no clinical studies of stepmothers killed exist.…”
