After I moved in twelve years ago, an elderly guy from the other end of the block would stop and chat with me while I worked on my fixer-upper house. He served in the Navy in the Pacific during WWII. I would gladly listen to any wartime story he would tell me. In the early years, he was great to have around. About a year before his death, he became senile-mean (to everyone), and was tuning in&out of reality. He died in the tub.
In those six-seven years, I had never met his wife (ex actually - whole other story) who lived under the same roof. By reputation, she was considered a loon. The first year after his death, the yard (and house) started going downhill fast. I heard through a neighbor or two that she had contracted with some yard service that first summer. They took her money, mowed the yard once, and were never seen again.
My dog and I walk everyday, and I would think to myself as we went by, that overgrown yard is practically a postage stamp. So unannounced, I started mowing her lawn. That's how I ended up meeting her. She IS nutz, and not well off financially. To make an already long story short, I now park my '56 Chev in her otherwise empty garage in exchange for cutting that 20-minute lawn, and other small project work outside the house. She is one of those hoarders you've seen, read, or heard about - so I make it a policy not to visit or work in the house for a variety of reasons.
Since they had no kids nor local family, she doesn't really have any trustworthy people to look after her. She has been taken advantage of by door-to-door people, so-called friends, etc. One scuzzy woman friend (a fired bus driver with a drug habit - I think) is pilfering her blind, but she refuses to see it or admit it. She's lonely enough that she must be willing to let it go. The widow and her (ex)husband used to own and operate a british/import car repair shop. I never knew it from all my years of chatting with the old guy that he was a retired british car mechanic (Somehow, I had thought he had worked as an appliance repairman). When she found out I liked cars and working with my hands, she went looking for her husbands remaining tools - gone (along with other things like a few musical instruments, service medals and awards, etc). She didn't know when or who took them, but I suspect the scuzzy friend based on things I've witnessed or heard.
She has had to have some plumbing & electrical work done to the house the past couple of years, and even local well advertised and seemingly reputable companies have abused her trust and money - I've seen it first hand. I've offered to interview service people she wants to hire before she can get taken advantage of, once again. She always agrees to do so, and never calls. For people with dishonest intentions, she is just what they are looking for.
After I started volunteering the yard work, a few other neighbors have helped out in other small ways. Collectively, we can't protect her, especially from herself...
