What was the result of evidence against Gibbs that Abby uncovered in NCIS?

It's impossible to provide a specific answer to this question because there are multiple instances throughout the NCIS series where Abby uncovered evidence against Gibbs.

To get a more accurate answer, you'd need to specify which case or season you're referring to.

For example, you could ask:

* "What was the result of the evidence Abby found against Gibbs in the episode 'Heartland'?"

* "What did Abby uncover in the investigation of Gibbs' past in Season 10?"

Please provide more context so I can help you find the specific information you're looking for!
