That's really sad that she passed away without being able to find her son's remains and give him a proper burial.
I hope she comes back to haunt Brady to the end of his days.
That may be all irrelevant now.
If you want to believe that the end of our lives are not the end but just one door closing and another opening, her boy was there to meet her when she passed over or summat.
Nearly 50 years of living the torture she lived, death is a blessed relief, she is with her son again.
