I just got an idea, and I am posting it here. It is not quite about the girls, simply, what to do with all these tips.
I think that the tips database that the Delphi murders case has created might be the largest one in the country, as the reward is huge. And it is very likely that some serial killers are in these tips. Maybe the Bridge Guy is not, although, unlikely, but in itself, the tips, the names, present a huge raw database.
So… I hope that for what I propose, one can simply write a search program. And I propose to use the tip names pool as the database.
Say, there is a name in the tip pool. For this name, one has to write all the addresses where the person has lived (phone numbers, too). And then, write all addresses of his/hers parents, aunts/uncles, grandparents, children, nephews/nieces. Maybe even best friends.
And then make a raw list of all disappearances, murders, sexual assaults in the country.
And run one list against the other. One could change the parameters, such as “within 10 miles”, or “within 30 miles”.
(Another run would be running phone numbers agains the lists of ones that pinged at nearby cell towers on the day of the crime).
And when there are matches, check the dates - if these people could physically be at the places around the murders.
I think this comparison might allow to catch several serial killers. Not necessarily involved in the Delphi case; I am now thinking that “tip bases” could be combined.
I think that all of it can be done via programs.
The idea came from DNA criminology, where the element is building and comparing trees. What I thought was comparing “address trees” with “sexual crime” trees, since modern sex offenders know better than leave DNA. But they have to know the places of their crimes.
Someone mentioned that the Delphi LE group is very small. Small group dealing with large tips base is not productive. While tips can be submitted for different reasons, I believe that “scared” might be the uniting world.
What further filters to use for the names one gets - maybe mode of killing/attack? There is a reason why Delphi and Evansdale are combined, or MB’s case is mentioned there.
In short, when there case has stalled but there is a wealth of information, it can at least be used for other purposes?
