My research has suggested I need proof to validate my accusation
You already have the proof. She doesn't need to know that.
Ok so imagine you and I are at a poker table. You lay a big bet on the table(this is you saying "I know I have something" or "I am bluffing".) I try to figure out which it is(im not sure because you didn't tell me what info you have).
If I look you in the eye and say "prove to me that you have a good hand"; would you?
You have the upper hand in information. If you concede that info you are disadvantaging your position.
She will either break down and confess all info, some info or will deny everything. Give her the chance to burn herself before you do. That way you know whether she is telling the truth or not. Having proof is good. Telling her what you have is a guarantee for her to only admit to that stuff that you know about, go fully underground, and keep on trucking with same or different OM. My$0.02
