It’s been stated that the two sketches are two different people, but first sketch is no longer a person of interest and now second sketch is BG, the killer. I would think they identified person who was original sketch and ruled him out.
This is how second sketch came about:
“The sketch artist with ISP who drew the face, Master Trooper Taylor Bryant, told the Indianapolis Star the picture presented as being new Monday had in fact been drawn Feb. 17, 2017, three days after the bodies of the two girls were discovered.
In vague terms, Bryant told the Star the
imagewas based on the description of a man by a witness who reported seeing something they felt needed to be reported. The sketch is a "ballpark estimation of what the person looks like."
Bryant, who did not draw an earlier, widely-disseminated sketch released by police that showed a much-older looking person of interest, told the Star he creates his drawings based off how a witness describes a suspect using a "facial identification reference sheet," which allows people to describe a suspect based on various categories such as a person's head shape, style of eyebrows or type of nose.
"The witness is the main focus,"
he told the paper.
"So there’s no input from law enforcement at all in the generating of a sketch, other than my presence as the artist."
BBM that last part is important because I’ve seen WS posters suggest they released new sketch to fit more with a suspect they have. Which would be detrimental in prosecuting that suspect IMO. But this article clearly states that second sketch came entirely from a witness 3 days after girls were discovered who was reporting something they believed needed to be reported.
