Deceased in rental property disclosure Ohio

I have a rental property in Columbus Ohio area. Someone recently died on the property that is likely a homicide. Couple questions.

1) A couple lived there and the husband is likely going to behind bars for a long time. May rent is already paid. Do I have to wait until June 1st to take over the unit?

2) Does this need to disclosed to the next tenant until the end of time? I understand in a sale it is likely disclosed to buyer but to new tenant? 

It is sad when a tenant that was staying for 4 years and paid on time every month have to leave like this..
