Owners Liability while holding land

[Thayer Hood]

Hello BP, I have a question regarding an owners liability while holding an empty lot in a residential neighborhood.

The lot is between two properties and is in a run down area (Low to mid C). The lot has become active with drug users and occasionally has needles left.

There is no fence and we will not be putting one up. We asked the police to keep watch for drug use and there is a no trespassing sign.

This lot is in Indianapolis, IN and I want to know if something happens to a child playing while entering the land or if someone ODs (praying this doesn’t happen) what our liability is!?

Please help, any and all advice is appreciated!
