There is evidence that child abduction killers are 6 to 12 times more likely than other murderers to bind their victims. In one-fourth of the cases the killers bound their victims, compared to only 2 percent in child murders and 4 percent in all murders.
The much more frequent binding of child abduction murder victims reflects both control and sexual elements. Binding a victim makes control easier, and for uncooperative, strong victims it may be absolutely necessary. For child victims, this control function of binding is less critical. But in these types of murders, with their strong sexual component, the binding (or bondage) is more likely to serve more primary sexual functions. These victims are
being bound less to physically control them than to fulfill the sexual fantasies and needs of the killers.
The source of the binding material is known in 87 percent of the cases of binding.
Of those cases in which the source of the binding material is known, 67 percent of the killers brought the binding material with them to the crime
scene.
This has evidentiary implications for matching binding material found in the possession of the killer after he is
identified.
