Sorry for your daughter's distress. It is possible to tweak things a little as in "enhanced" forensic pictures say from CCTV but the result is subjective and in most cases hardly worth the effort.
Adding to BT's suggestion, it could be that at the 21st, someone strange to the camera in the excitement of the event simply jabbed the button instead of slowly does it and so not give time for the camera to lock its focus. This would be easy to do on an older /cheaper camera.
It is unbelievable I know, modern cameras are idiot proof.
I thought it may have been a greasy finger on the lens, problem being we cannot go back in time and re-stage the events.
Thanks for the help.......you all know it is MY fault if I cant find a solution although I never took any of the photos.
