@Springmisttyshaw it’s onus, not owness you have used the incorrect homonym (although the two words are not commonly recognised as homonyms, like right and write are, for example).
And I hear similar instructions from clients/defendants and the OP’s actions would be defendable. She secured her property, she proactively reached out to try and find the owner via social media, she spoke to Police and FC about options, she engaged with a representative of the owner (DS) and later the owner try and negotiate a time for collection, always ending with offering an available time.
The car owner on the other hand, has abandoned his car despite a warning, not knocked on the door of the home, not put anything on the windshield or mailbox or at the front door, and not made contact for days. When he has, he insisted on one time and would negotiate to an alternative time. He then appeared at the un-agreed time. He hasn’t appeared again, or made contact again.
You’re post thinking the OP doesn’t have a defence is incorrect.
Either way, this is not at that stage yet, and the OP should (as she is) keep the Police informed, and not listen to people trying to scare her when giving legal advice on the internet.
