Discrepancies In The Sandy Hook Shooting Case

Does anyone else find it extremely weird that a Facebook page honoring Victoria Soto, the teacher shot by Adam Lanza on December 16, 2012 in Newtown CT, was put up on December 13, 2012? That is 3 days BEFORE the massacre. Why is that? I am posting screenshots of the Victoria Soto memorial page on Facebook showing the page was created on the 13th, and activated on the 15th, the day before her death. I’m not into conspiracy theories, but this is odd.

Also, according to genealogy.com, Adam Lanza, the shooter, died on the 13th. If so, he couldn't have been the shooter.
