We, my neighbors and I, park cars in our yards, for a small fee, for a certain yearly event. One year I was taking care of my neighbors property since he was unavailable. I had a car pay to park and then never returned. A couple days after the event I decided it was time to deal with it since the cars owner had not returned. Called the local POPO, they called the sheriff in the town where the car was registered. The sheriff went to the registered address and spoke to the owner who subsequently said he didn't care what happened to the car resulting in the POPO removing it for me. This obviously was not a normal case of trespassing but it was effectively abandoned on property I was responsible for.
