I'm trying to nail down a few difficult to find things for study. One of them is the complete steps in order for Chain of Custody. I've ready some sources that say the image is first, I've seen others that say documenting everyone at the scene or involved is first. I'm looking for an actual order.

I'd also like to see the supposed chain of custody form that might be commonly used for security professionals. I've googled it of course, but there's so many I just wonder if there's one more geared to our profession than say CSI
