The "girlfriend" story sounds like a "cover", to me.
Unknown at this point is whether there was more than 1 shooter. Were I in charge? Like bloody hell, I'd go on tape announcing there were other shooters live and on the lose in the community, in another state, etc. I'd be collecting evidence and following tracks.
I'm not trying to be light on this score; but what if the shooter's name happened to be "Ho". No id, no face on the alleged perp.
Ho is an actual family name in Vietnam.
That depends. If his first name is "Napi-hedded", we'll never get to here it on the air. There isn't a (working) radio/TV person who'd dare utter THAT phrase.
