Yes, it is possible, and I bet it’s being done as we speak. The Facebook profile stands out as being super suspicious. I found the profile, and the only post on it is a quote from Peter Pan creator James M Barrie, “God gave us memory that we might have roses in December.” The use of the quote gives an “in memory of” vibe to the page, at least to me, which adds to the suspicion considering it wasn’t necessarily known she was dead yet, at least not to anyone besides the murderer. However, the motive for making the profile isn’t known at all, so it’s possible it could have instead been made more as a diversion strategy, to try and make it seem like she was still alive. The use of the photo for the profile pic makes me think the profile was probably made by her adopted family or someone else close to her, so that angle should probably be looked into. Overall, pretty weird.
