    your second comment? i don't see any relevance to what i posted.

    and yes, statisitcs matter b/c they help determine which possibiliites are most likely. this is why NCMEC, the FBI, the DOJ etc. keep them.

    in a nutshell, the chance that each of these three girls being taken by an intruder is just infintisimally small. and that is just oh so very sad.

    It means nothing really. It is only as good as a statistics when you know the facts of this crime after the solution.

    All that matters is that it happens and has to be considered a possibility.

    I don't care about statistics, not when it comes to looking at possibilities.

    What matters is looking at all the options and seeing what fits. What may have happened in another case has bearing here.

    let's look at the probability of all three of them being taken by an intruder:

    stats on child abduction:

    1) Research shows that of the 58,000 non-family abductions each year 63% involved a friend, long-term acquaintaince, neighbor, caretaker, baby sitter or person of authority; only 37% involved a stranger (aka intruder)

    2) Each year there are about 3,000 to 5,000 non-family abductions reported to police, most of which are short term sexually-motivated cases. About 200 to 300 of these cases, or 6%, make up the most serious cases where the child was murdered, ransomed or taken with the intent to keep


    (taken from NCMEC and the US Dept. of Justice)

    the math: http://www.mathgoodies.com/lessons/v...nt_events.html

    P= probability all three crimes were committed by an intruder

    P of independent events = P(event a: JB "abducted"/intruder) x P(event b: MM abducted/intruder) x P(event c: LI abducted/intruder)

    P= P(.37) x P(.37) x P(.37)

    P= .0506

    therefore, there is a 5% chance all three crimes were committed by an intruder.


    (i believe my theory and math is correct... but someone please tell me if i've erred -- thanks)

    now, if we take it one step further and use the second stat i've included above-- the one for "the most serious cases where the child was murdered, ransomed or taken with the intent to keep**" as seems to be the case for JB, MM and LI, where an intruder is involved in only 6% of these cases (**and so far each of the three cases mentioned in this post meet this criteria imo w/ both MM and LI being classified under "intent to keep" for this exercise):

    P of independent events = P(event a: JB murdered/ransomed/intruder) x P(event b: MM abducted/intruder) x P(event c: LI abducted/intruder)

    P= (.06) x (.06) x (.06)

    P= 0.000216

    therefore, a less than one percent chance exists that all three crimes were committed by an intruder who desired to murder, ransom or keep the child.

    ***and yes i know the MM crime occurred in portugal and not the US but i couldn't find stats for the country nor do i believe it would skew/change the results too much
    Hi, redheadedgal. It's amazing that you could put this into a mathematical equation to calculate the chances of all three of these cases being an intruder. Everyone knows that statistics show, in child-related crimes, it is most likely to be a family member or someone within their inner circle who is responsible. That doesn't mean that any one single case can't or won't be an "intruder" -- but statistics being what they are, this is the reason investigators look first at the family in order to eliminate the most likely possibilities. It's sad, if you are in the situation of having lost a child, to think that you will have to go through the scrutiny as a suspect at a time when you are so emotionally distraught; but knowing it is a necessary step in the investigation should be enough for anyone to be willing to cooperate and get through it in order for investigators to move on toward finding who is responsible.

    On the math... I know the probabilities in a coin toss of it being heads (or tails) is 50% each time it is done, regardless of how many times it is tossed. That strikes the casual observer as impossible because you would think sooner or later it's got to be the opposite. And that is also correct. The difference here that throws most people off is whether you are looking at each individual coin toss (where it is 50% each single time), or the total amount of tosses (where you are looking at the total amount of tosses). If you toss a total of five times, each individual toss has a 50% chance of being heads (or tails). But with each successive toss, the chances of all of them being heads (or tails) is compounded exactly as you calculated above. So even though each of the individual five tosses still has a 50% probability of being one or the other, the chances of all five being the same would be 3.125% [ (0.5) x (0.5) x (0.5) x (0.5) x (0.5)].
