His apartment was across the street from the Waffle House. He ran back to the apartment after the shooting. He could have deleted it then or law enforcement could've asked Facebook to remove it.
Most likely, he deleted it himself as there are plenty of Facebook accounts of criminals and killers that remain on-line.
Has there been any info anywhere on whether or not the perp was currently being treated for mental illness?
Why on earth would law enforcement want to cover up evidence like that for all to see?
The speed at which FB accounts disappear when there’s a mass shooting makes me think FB is the one doing the deleting.
There is another FB account which is up.
