i think it has something to do with dental records. the conversation he had with the woman mentioned a dentist.
News report said dental records matched Lalo's proving he's dead.
at first i thought ZZ top was a dentist but i think Lalo needed his teeth? it didn't make sense to me so hopefully someone else can clarify.
