IMO the entire interview is a real punch in the gut and totally disheartening.
He won't openly admit it (obviously), but reading between the lines and interpreting all the pauses, deep sighs and "Uhhs"...LE have absolutely NOTHING. They aren't one step closer to finding the perp(s). They don't even know how many perps there were. There is no video or audio of the crime itself, they likely have released just about all the evidence they have, and there is zero useful DNA evidence.
He is trying to play the "protecting the investigation" card, but judging by his responses and the deep sighs and his tone of voice even he is tired of trying to convince anybody of that. He's just sticking to the script. He compares it to a poker game where they need to keep their cards close to the vest...but IMO this interview revealed that investigators have a crap hand. We can't see his face, but he definitely does not have a "poker voice".
IMO the "twist" he's referring to is that they have an image and the voice of the guy and all these resources available to them and STILL are at square one three weeks into the investigation.
I hate to be so negative, but this interview is the clearest indication yet that they need the luckiest of breaks to ever solve this crime. This is truly heartbreaking.
PS: Without the glasses and mustache even Sheriff Leazenby looks like the suspect. Same chubby baby face and wide nose. No, I'm not suggesting that he's involved, and please don't go sleuthing the man. Lol. Just pointing out how the image of the suspect is so generic he could be anybody.
