Just a small digital forensic reality check here:
There is absolutely no way that ANY agency can say with certainty, 24 hours after learning an alleged perpetrator's identity, that that individual "had no electronic contact with the victim."
It is simply not possible.
Until today--theoretically--police and FBI and other agencies had zero knowledge as to the identity of the accused (right?)
There is no way that within 24 hours these agencies, now suddenly learning the accused's name, were able to pursue and eliminate every possible digital forensic trail. My god, it takes months, sometimes, to even determine what someone's various usernames are/were.
It is not physically possible to eliminate all possibility of digital contact between two individual in under 24 hours. Entire agencies, in fact, exist because of this impossibility.
I'm sure police were being honest when they said they had no knowledge to date of electronic contact. That does not mean electronic contact will not be discovered.
I don't mean consensual contact; I mean whether or not he was stalking her. That cannot possibly yet be known, as they only learned his name in the past 24 hours. It will take many, many weeks--possibly months--to fully understand any online presence he may have had.
