I’d agree but it’s hard to believe they can’t, over the course of a full day have a name and prints to match just by asking some of the girls friends who she was seeing. Also it doesn’t make sense that this guy would care about being ID’d if he was an enraged lover and obviously he didn’t.
You have to quit assuming it WAS a boyfriend. The police are still denying this element. Additionally, there are many times a girl is seeing someone and keeps it a secret; for many reasons. Who knows, if it WAS a boyfriend, or a fling, or whatever, maybe the “shooter” is married. There are so many scenarios one could imagine; so many possibilities.
