Likely neither of them will be found guilty in a civil trial, much less charged in a criminal trial
For once I agree with you - to a point. There is a great possibility that some or all of what you indicated may come to pass. However, I am quoting the law. And here you have a situation where under either civil or criminal law - assuming sufficient evidence - Woolsey, Egan, or both could be formally subpeoned, and made to stand trial. Regardless of what happened to Woolsey, a very clear line of responsibility in both civil and canon law can be shown leading right to Egan's door. Sorry - no "free pass" for priests, as you put it. They must start living the gosple - not living off of it!
As I read this story, there is only the civil action. I don't get the impression the family is pressing a case with the DA.
