From AZAG.GOV:
Elder abuse is a serious problem. In Arizona, between 4,600 and 6,900 seniors will experience some type of abuse each year. Reports of abuse have increased 150% over the last decade. Older adults may become vulnerable due to isolation, physical or mental disabilities and dependence on others for assistance. This vulnerability makes them easy targets for physical, emotional and sexual abuse, neglect, financial exploitation and fraud. Abuse always occurs when there are no witnesses.
