I need your full attention, Saul. Jesse Pinkman current whereabouts. The sooner you tell me, the sooner you can get back to whatever the hell this is exactly. Whoa, you are good right there. Now lets both get comfortable. Now when I say I'm looking for Pinkman, we both know why, don't we. And you pretending otherwise only wastes my time and serves to annoy me. I trust the hole in the desert I'd leave you in. Don't make me beat you 'til your legs don't work. Now tell me where to find him, you know it's the right thing. 

Once you call it in, the people who show up with be with the office of medical investigations. it's primarily who you'll talk to. Police officers may arrive they may not, depends on how busy a morning they're having. Typically ODs are not a high priority call. There's nothing here to incriminate you, so I'd be amazed if you got placed under arrest. However, if you do, you say nothing. You tell them you just want your lawyer. And you call Saul Goodman.
