I have a theory...No scent outside car, only inside at j's work. No decomp in car. We know R was at the Bank, Car parts and didn't get out of the car at the car parts. I feel like he took Hasanni out behind the parts place where there is lots of roads and places to leave a child. I don't think he did anything except leave him. He had texted J about leaving Hasanni at the Bart. Too many people. Also his car was spotless. I think he got the car washed before heading to J's work. When Hasanni is found he can say see someone took him.
I thought they should search W. Winton Rd. but no one wants to search there. It's a very secluded area where W. Winton seems to split into 2 roads. One is gated, but not the other.
