Hi, my mother has dementia(89) and walking with a rolling bag around her apartment complex occasionally picking up other people's UPS packages and bring them back to her apartment. For the past 2 weeks, she is taking magazines and candy from Target and a local Walgreens. She has a caregiver with her, but she will still steal and deny it or doesn't remember. She has money. So that's not a reason. Her apartment complex management has this on video and threatened to get police involved because of missing packages. Any suggestions? Thank you.
