Itās probably nothing to worry about; if I was going into the hospital I would specifically bring an inexpensive rosary with me. The family was probably telling the truth when they said it wasnāt a āspecialā rosary.
The others in the Operating Room may not have even noticed the rosary, and it probably got damaged in an accident. At least they were aware of the fact that this was something important - they saved the pieces in probably what was the best way they knew how.
The person who broke it may have not realized it, or it may have been a group accident, or the person may be so embarrassed that they donāt want to 'fes up, but are genuinely sorry for it, especially if they think it was something much more important than it actually was.
