I think we are looking at a version of Constain Drakon from the comics, as far as who he is in the show, it's not Roy, it is someone close to one of the people Oliver took down in the first season, likely from one of the very first epsisodes. As far as knowing about the list and Olivers real idenity, Tobais Church revealed that to Prometheus earlier in the season, and we also have the Artemis factor. SCPD access? Star City has issues with corrupt cops like most cities of its size. Someone with the right minor connections to SCPD could get access to the evidence locker. I think the whole SCPD thing was meant to throw suspision on Billy Malone. And its not Justin Claiyborne's wife Ollie visitied, it was his mistress, so if he is actually Caiybornes son, then he is his "illetimate" (as much as I hate to use such labels) son.
