Such a informative post Thankyou. Makes me think of a case here in Australia, William Tyrell.
His body has never been found but such a insightful post could apply there too. Have you ever posted there?
No I haven't, but in general the profiles of the types of individuals that commit abduction murders of children for sexual purposes, doesn't change much at all.
Sure there are exceptions, like time spent in prison , but in general, its usually someone in their late 20's early 30's that lives or works nearby. It might also be someone who travels through that area regularly. (IE they usually operate in area they are somewhat comfortable with)
The victim is targeted just because there are no adults, the presence of other kids usually wont deter them once they have committed to the action.
The motive is so often sexual i'm almost tempted to say "always" but science has taught me not to.
A vehicle is used in the overwhelming majority of abduction cases (teach your kids to never approach a vehicle with lone adult ESPECIALLY if that adult is a male, whether they know them or not, and to fight like hell to get out of one if they are put in it)
The offender almost always acts alone.
The Victim is most often deceased within 1-3 hours of the abduction, which is alarming, because MOST cases where the abduction wasn't witnessed an initial report is made approx 2-2.5 hours after the child was actually taken. Which means in MOST cases, the victim is already dead before they have been reported missing .
The victim is usually transported over a mile
The body recovery site (I hate to use the word "dump" it takes away from the dignity of the victim) is often well known to the offender, that's where he stands the greatest chance of being seen
The body recovery site and the murder site are often the same area, if you think about it its much easier and less riskier to move a live victim, even after they have been assaulted. If the police find them alive with the abductor, its not a murder charge. If they're found with a dead body, its a murder charge.
For this reason, many victims are assaulted and killed in a vehicle, or taken somewhere they wont be seen, for the same fate, which explains why strangulation is the most profound method of killing a victim. Because of evidence transfer methods such as stabbing/cutting, bludgeoning or shooting a victim are usually done outside a vehicle, though it has happened.
The victim is usually hidden to avoid detection as long as possible
The offender in many cases, returns to visit the body site, usually within 48 hours of being left there. Sometimes "re-live" the event, sometimes to simply to see if the body is still hidden well enough to be undetected.
There will be an array of post offensive behaviors that to the trained eye will stand out, theres usually a sudden and intense interest in the case, they'll often change their appearance, they'll gain or lose weight, they may increase the use of intoxicants, they may "shed" or inexplicably get rid of certain items with little to no explanation, they may offer clues, such as being in that area that day but deny any involvement, as a type of pre-preemptive defense "Wow I was there that day, I didnt see anything" or offer outright false information , they may actually confide in someone, they may offer to help the investigation, And as often is the case, they may all the sudden move out of the area.
This model is so consistent many agencies begin with this and build off it in these types of cases.
