Uh wtf did i just witness?

I was walking by a gas station and there was this middle aged woman holding a baby in just a diaper. Who stands by a gas pump just holding a baby but whatever. Then this black Escalade rolls up but stops when it sees me and its like I'm being watched by whoever is in it. I start walking and it moves closer to the woman and she goes up to it.

Idk if it's a drug deal or if she's selling the baby or what.
