illegal trash and dumping

Earlier this year some tenants of mine moved out of our rental. We began to do small jobs in the home after they moved out. Shortly after this, we tried selling the home and unfortunately were not able to. The home was vacant for 6 months until it was taken off of the market and I decided to have new tenants move in. They have been there for almost 2 months now. Yesterday I recieve a phone call from someone who works at the County Environmental Agency telling me that there is a criminal investigation going on because they had found some illegal trash (paint,oil,tires) that was dumped along with some mail which had my previous tenants names and the address of my rental home. The current tenants told me that the police dept. had spoken to them threatening them with a felony and interviewed some of the neighbors. I don't understand what's going on. Does this affect me in any way? We had done some work on the house 6 months ago but everything was disposed of PROPERLY.

It should not. The illegal dumping of trash done by tenants is not your responsibility. We assume you did not do it as well.
