All speculation, imo, thoughts for now, fwiw.
It seems like every time i look at that pic of the suspect, my perception of what he looks like changes.
Sometimes it seems like a young guy with light hair and a broad baby-fat face, other times like a " middle-age fat dude " and sometimes he seems like a hard-faced, dark-haired, moustached, and wiry built, guy.
Occasionally see him as someone disguised in some way, maybe even wearing clothing and footwear that is too big, perhaps causing his foot to turn outward.
He looks like almost any guy, from anywhere and maybe that is why he almost gives off a " honey-badger don't give a s*** ", vibe.
