I think we might actually have the name of Andy's boyfriend? If you go back to the scene where he shows MSF his picture (after the jealous kissing at the club when MSF goes out with TY while still wearing the Kermit shirt)... That's the only plausible place.

I don't have my computer right now so can't check, sorry!

Also, yes, a police officer using "Lao-" with a mob boss he's familiar with, maybe frenemies with, is totally a thing that could happen. Go ahead and use it!
