Tadpole12,
It might be possible to describe some of JonBenet's injuries as
Piquerism, particularly if JonBenet was assaulted internally for this purpose, there are other interpretations of this behavior.
Dr. Wade Myers has a short section on piquerism in his 2002 book Juvenile Sexual Homicide.
Piquerism is sometimes performed post-mortem. It generally refers to the penetration of human flesh, although it is sometimes practiced against animals. The piquers range of activities for sating his or her needs can be a purposeful single prick with a pin or knife, multiple stab wounds to an eroticized area, or elaborate cutting, stabbing, biting and mutilation of a victim. Piquerism becomes part of the repertoire of many sadists, depending on their progress along the sadistic learning curve. Often the sexual mechanisms inherent in piquerism are ignored during the assessment of sexually sadistic crimes. The prevalence rate of piquerism is unknown.
In that alleged time period between the head blow and the asphyxiation did JonBenet's assailant think JonBenet was dead, so proceeded with apparent postmortem behaviour, which was really perimortem, or simply did not care?
Given what Kolar has hinted at I reckon
Piquerism could be used to describe some of JonBenet's injuries, particularly the use of the
paintbrush which I'll assume had a pointed end?
Sometimes in homicides involving
Piquerism the killer likes to remove a trophy item, e.g. Knife or missing piece of the paintbrush?
I'd like to link your idea of
Piquerism with that of
Scatophilia i.e. a morbid interest in excrement, both are paraphilias.
I reckon we can associate
Scatophilia with the case given what was found in JonBenet's bedroom, and slightly more tenuously
Piquerism, which needs a definitive example wrt JonBenet.
