It almost seems that Ilona was expecting trouble of some sort. To call jails or hospitals immediately because someone is a no show for two hours seems odd to me. Even more puzzling is Sal's phone taken from the car but placing a text to Gianni at 1:30. Wasn't that actually after the killing? The shooting being at 1:14 AM.
I am wondering how LE could establish whether they owed any drug debts. It's not like it shows on a credit report. IMO no drug dealer is going to expose their accounts recievable to LE. I would venture to say that drug dealers are not the most credible witnesses or sources.

True, and if they did happen to find their dealer, it's not likely he'd pipe up with 'the kids owed me a ton of money' as that'd make him quite the suspect.
But how could they afford such a costly habit? Neither worked high-enough paying jobs to be able to fork over 250. every single day of the week.
