Stealing from nursing home residents or hospital patients is nothing new. Happens ALL the time, sadly.
The worst thieves are the "court appointed guardians" but it is rarity to find a nursing home where there isn't someone stealing from the residents.
In this case, surprisingly, she did not actually steal that much. Known several cases where the thieves had ripped off hundreds of thousands.
It takes a special kind of scum to steal from the elderly the ill and the dying.
