Cemetary Entrance
The evidence for this is towards the lower level where the four paths meet. You'll find the evidence on one of the stone walls coming off of this intersection.
Burnwood Family Tomb
Make your way down the path and take a left. You should be facing the spot where Jade is talking to the people digging out the grave. There should be the mine and explosives off to the left side. The evidence will be on the far side of the dig site on a stack of boxes.
Crematorium
You can find this evidence by following the mission walkthrough. You'll find this just down the steps from where Travis is holed up. Check on top of the black boxes and you should find it. Just be careful of the explosives nearby.
