Tracing who deleted a role from the system

Is there a way to trace who deleted a role from the system (not from a user account but the actual role via pfcg)? We have looked in SUIM, the AIS, and the SAL with no luck. The SAL does not give the best data. Not detailed enough...

I'm afraid not, though you may be able to track history through the role's profile.. Try running suim for change history on Profiles, and look up activities against the deleted role's profile.
