So it's recently developed but not a new tip. Hmm...
One possibility......
Kaine got home not too long after Terri uploaded the Science Fair pictures to facebook.... upload 1:20pm and Kaine got home 2pm - 2:30pm. So only 40 minutes to an hour or so in between.
I think it is possible that investigators were only working with the time frame
before that upload. We haven't heard any requests for if anyone saw Terri after 1:00pm (that I have seen.) They may have assumed that she really was home.
They may have followed cell phone pings to the island...then thought that was a red herring left by Terri when they didn't find anything.
However, I think investigators may have recently realized she may not have been home at 1:20pm when the pictures were uploaded. They may have verified that by tracing back the IP to the island.
Since the pictures were uploaded, they know someone was there, unlike the cell phone pings. That would lend more credibility to where the IP address traced to and it would be less likely to be a red herring.
Yet, they still wouldn't know where she put any evidence, just that she was on the island. The same could apply to cell phone pings, if they were able to place the phone in her possession somehow.
If they had both the pings
and a traced IP, that would be especially compelling.
This would justify a more extensive search.
This would be also
newly developed information from an
old tip that has been known since the
very beginning.
