Someone stole my Mother's check book from the nursing home. Luckily we had set a limit on the amount a check could be written for, and limited the amount held in the account. The person was caught, she turned out to be "one of the better nurses" that had been taking care of Mom for the past eighteen months. She wrote a check for an amount well over the amount in the account at a high end department store. They accepted the check with no picture ID, just the word of the nurse that the name on the check was her. Her picture was recorded on a closed circuit TV, and she was identified by the detective that worked the case from his meeting her at the nursing home while taking a report from Mom. She had to make restitution, and served two years for theft by deception.
I agree, and speak form experience, patients in nursing homes should not keep large amounts of money, credit cards, or expensive jewelry. If you have relatives there, you need to check it out, or have someone the patient trust do it. An ounce of prevention......................
