There's a nice garden on the side, it looks like it would be the perfect place to calm down.
A bucket and rag can be seen near the unlocked shed.
The shed has a duffle bag and a rake, shovel, and other gardening pesticides inside. The duffle bag is empty. It seems like the mastermind is cueing you this is a spot to hide a body.
One of the sheds are locked. A small hole is in one of the walls, you can see plenty of watering cans and a basement door inside.
