5 day overstay on visitor visa

[Srav359]

I have applied for B1 visa extension for my Father & Mother on same application. I have received acknowledgment from USCIS. But My father has left US earlier before the application was processed and my mother stayed back. eventually after 4 months after application submitted...I got a reject notice stating that the applicant ( my father  & my mother is co-applicant) left the country and request for visa extension is rejected.  My mother left US 5 days after we received the reject notice. 

Now question is will this make my mother B1 visa invalid? and does she need to attend visa interview again to get a new visa? 

My expectations is my father visa is still valid.  pls comment if my expectation is not correct

Thanks for experts comments

If she stayed past her I-94 expiration date, her visa became invalid as soon as the application was denied.

Thanks for the response. I will have my mother attend Visa interview again. as my father left before the denial ...I expect he does not need to attend Visa interview again?

thanks
