>>Use your COMM JACKER 3000 to SNOOP his communications. If he's messaging Mr Hubbard then this case will be SOLVED.
You whip out your SPY PHONE, boot up that fancy COMM JACKER 3000 program, and sit down at a nearby bench while you read through the 20 or 30 pages of terms and conditions needed to actually
use this thing, until you finally scan past a spooky warning about how 'this app isn't officially endorsed by [your spy organization]' and how the phone 'is likely to explode after multiple failed attempts to unlock it' for security purposes.
You are STALKER, and you realize that your briefing didn't actually include the milkman's phone number...amateurs really.
Luckily enough everyone here's dumb enough to keep their GPS on, and you quickly catch on to the Milkman's phone, retrieving some data packets your COMM JACKER determines to be HIGHLY ENCRYPTED messages.
You sit and wait patiently for the messages to decrypt, finding your first packet to contain the following exchange.
Milkman: Hey John, guess who's wasting most of their morning today?
Lenor: You?
Lenor: And don't use my real name here please.
Well that was useless, I
guess Mr. Hubbard's first name is JOHN, but uh, this doesn't really prove much.
You bide the time between decryptions by.
>STALKING John Hubbard's social media as well! Might glean some interesting info.

>Send the Milkman a message on Telemessage, everyone's favorite 'eNcRYptED' messaging app now that you've got his ID.
