Links between IPF and homicide concealment have been observed but not explained. We theorize IPF perpetrators use concealment to continue coercively controlling investigators, children, courts and finances post-IPF. We compare abuse in the relationship and surrounding IPF in five diverse cases. Facilitated by concealment, offenders use versatile, subtle and overt tactics to extend control post-IPF. They capitalize on opportunities for concealment and regaining control, sometimes without other benefits. Tactics are akin to those employed previously, aligning with the power and control wheel. Concealment allows offenders to dominate the death narrative and assists with remaining unaccountable.
