In the aftermath of the killings, media commentators frequently cited Genetic Sexual Attraction (GSA), a controversial phenomenon where adults reunited after prolonged separation report intense, confusing romantic feelings. Clinicians and criminal justice experts rejected the idea that GSA explained this outcome, classifying Steven's conduct as predatory grooming rather than mutual attraction.
Steven held every structural advantage: he was the elder biological authority figure, possessed economic resources, and controlled the living environment. Katie was a vulnerable 18-year-old searching for identity. By systematically alienating Katie from Alyssa, convincing her that their connection was destined, and isolating her from peers, Steven executed a pattern of domestic abuse and coercive control that culminated in familicide when his authority was challenged.
