I live in a senior housing complex. Recently the complex has allowed younger adults to live with their parents. One man has taken over the park and is terrorizing the seniors, intimating, causing mental anguish and despair by name calling, or by insulting, ignoring, threatening, isolating, and demeaning. As a result, some vehicles and homes have been vandalized; seniors are afraid to complain for fear of reprisals. Those that have complained have found the complex management is also scared of this individual. We are at a loss of what to do.
