I also live in Sagecrest and I think I may know who is doing this. Ever since last year theres been a guy on a bike that comes around and he always asks us if we need any work done in our yard when we are outside and we tell him no. He came to our door and asked us as well and we keep telling him no. One day he came to our door and asked us if we had electronics in our garbage and if he could look in our garbage and we said noooo. So last week I saw him up the road on Oster looking in garbage cans. I was so upset and told my husband to call the cops. Needless to say we did not call the cops because something happened between that time and he was gone when we got back. Next time I see him I will call the police. I've never saw him as a threat, just some guy looking for stuff.
