Drug dealers do not work in isolation.
The police are desperate to catch the guys at the top.
That means any of the dealers in prison are constantly tracked.
All prisoners have calls recorded and letters/emailed read but dealers even more so.
A lot of people dealers are close to like friends or gfs are usually involved with the drug dealing.
It doesn’t have to be actual dealing it could be driving him to a friends house or spending money but these are still classed as being involved.
And so anyone with contact with a dealer in prison is going to be checked out.
There are databases to check people out, all they have to do is type her name and they’ll see she’s on SS register.
She is a classic example of someone involved in drug dealing.
She had a child removed from her care, SS involvement, pregnant with a 2nd child but not with the father and now in contact with a drug dealer is prison.
They will likely have thought that she’s pregnant with his child which is even more chance of her being involved in some way.
If they think there’s anything romantic going on, then she is going to absolutely be on their radar.
