I can’t locate the articles at the moment ( they’re all posted up thread) but since investigators went to the campgrounds to interview the sister, and said that those grounds were part of the ongoing investigation, it seemed pretty clear to me that KA had been there just as the unnamed camper said, and had been dropped at Newark airport just after the warrant came out, for obvious reasons.Do we know for a fact that she was at the campground before May 18?
I may have missed something but I thought the unidentified male "camper" didn't provide dates for when he says he saw KA up there nor how long she stayed. He said she was there "right before the whole thing blew up". The arrest warrant was issued at 10:40PM on on May 17 but I don't think her name was linked to the killing in the media before May 20. And even then, it took a day or two to really spread nationally/internationally (earliest reference on CNN, for example, is May 23). The original thread on WS was created on May 21.
And the PI stated someone applied/obtained a NY driver's license in the name of KA's sister on May 17 but I don't believe he stated where in the state, i.e. was it in the NYC area or upstate by the camp. Not to mention it hasn't been confirmed that it actually was KA, and not her sister, who got it. If the sister was working for Camp Haven and planned on living there for awhile, she may have had legitimate reasons for wanting NY state ID.
The license is another matter, and may have legitimately been for Christine.
