DC has said more than once that the killer will probably look like a combination of the two sketches. People have stewed over that comment, calling it confusing and using it as an example of LE's ineptness. IMO, it says that the first sketch is not of somebody who was cleared in 2019, when LE changed directions, and that neither sketch is necessarily an accurate depiction of the killer, in and of itself. A combination could be anything...maybe a younger BG but with facial hair, or an older BG who looks young and clean shaven, or older sketch eyes with younger sketch nose...whatever.
Your suggestion about the sketch being a cross between TK and KAK could be possible, imo. I think the combination comment could suggest related individuals. Maybe.
@TL4S Something just popped into my mind and wanted to share with you:
Per the Indy star 4/23/2019:
Bringing renewed attention to a shocking case, Indiana State Police on Monday unveiled an updated sketch of the man they believe killed teens Abigail Williams and Liberty German in Delphi in February 2017.
The sketch shows a smooth-faced man with a narrow nose and thin lips. This face appears much younger than one shown in another sketch of the killer released nearly two years ago.
But this sketch is not new. The sketch released Monday was drawn on Feb. 17, 2017, a few days after the victims' bodies were found. The picture was based on the description of a person who saw something that the person felt needed to be reported, according to the sketch artist.
