Computer Forensic project; murder case

I need the evidence in the PDF made into actual evidence. For my Computer Forensic project I came up with a murder case and we have to create evidence to back the case. It will be about 8 pieces of evidence that needs to be created and I don’t really know how to accomplish that.
If it’s easier you can use your own methods to get the evidence created but I really just need help with creating the evidence created. In the document it’s mapped out how the evidence should be created so if you need that for guidance.

I need the evidence in the PDF made into actual evidence. For my Computer Forensic project I came up with a murder case and we have to computer physical evidence to back the case. It will be about 8 pieces of evidence that need to be hidden and I don’t really know how to accomplish that.
In the DOC files is the whole report with the tools necessary to create these pieces of evidence. If you would like to make changes to some ideas that can be done as well. The final result with everything should be in a zip file with the hidden evidence.
