In the opinion of The Four of Us, the most important study of very similar kidnappings, assaults and murders of victims like Holly Piirainen is entitled Case Management for Missing Children Homicide Investigation. The research was conducted by the United States Department of Justice and the State Attorney General of Washington state and was published in 1997.
A second study by the same agencies entitled Investigative Case Management for Missing Children Homicides: Report II was published in 2006.
The second study took the additional step of analyzing eight hundred solved cases of child abduction/murder from across the United States. The study found that, in a vast majority of similar cases (76%), the victim was a female slightly over eleven years of age, came into contact with the abductor in 80% of the cases within ¼ mile of her home, and was an “average child” living a normal life with a normal family.

These two studies identified another characteristic of this type of crime important to police detectives: in 74% of investigations, the name of the killer was known to police in the first week of the investigation.
