My very elderly father had cleaner who was stealing from him. To prove it he went out to collect his pension whilst she was there, put in in his desk, and looked in the drawer an hour later - it was gone. He confronted her, she denied it, but eventually gave him the money back and left. Only when she had gone did we discover that my mother's jewellery had also gone (my mother had dementia, Parkinson's and depression, and was in a nursing home, so her jewellery was kept in a box in her dressing table at home). We contacted the police, but they said no evidence to investigate. I dread how many other people she has robbed.
