Janice, very unlikely your group was hacked. Much more likely your list member's email was either spoofed, or possibly her email account password was hacked. When I have this happen on my list, I temporarily moderate the affected list owner...
If I had this happen to a list OWNER or MODERATOR I would (in addition to all your other good and sensible actions) IMMEDIATELY demote that OWNER to regular member status... because **IF** the password was hacked an OWNER can (at worst) delete the group, and a MODERATOR can exercise whatever privileges you've given them.
