Heavily Scripted Items, but can't find the owner

Hi, I was working on taming scripts on our lands, when I noticed that there were heavily scripted trees on the lot behind us. I did a Find for the owner to ask them if they could help with the scripts running in Slosser, but neither the land owner nor their partner can be located using the find option. I was wondering if this meant that they may not be returning to their land, and if possibly I could have some help with bringing the number of active scripts under control.

The land in question is in Slosser (246,141) it is a rather substantial plot of scripted land.

Thank you,

The trees on this plot only have the status of phantom set to them - this would not significantly cause issues for any sim, it just makes them able to pass through.

I performed a check on top scripts for the sim and nothing is showing up as being past a point where it should affect sim performance in any adverse way -currently-.
