It is easy to jump to the conclusion these two young ladies were catfished, and they very well may have been, in some manner, but as I read the following statement, LE does not make that definitive claim.
Detectives with the Delphi Investigation Seek Information
The second item I have trouble with is the apparent statement of fact made in this article, previously posted, and, well, here are the quotes directly from the dailymail article.....
"Indiana detectives reveal fake male model Instagram account - set up by jailed pedophile - was used to CATFISH the two 14-year-old Delphi girls murdered in 2017 "
"It's unclear if he has ever been questioned over the Delphi murders or if police think he is a suspect"
Cops link pedophile who was jailed in 2017 to Delphi murders through catfish Instagram account | Daily Mail Online
So for me, at this juncture, I'm just not certain of the part, if any, this anthony_shots and KAK thing plays in the Delphi case.
It sounds like the fake account was used to catfish the girls, but not by KAK.
