Sheep were poisoned by stealing wheat.

This matter is a neighbor's matter. If you can negotiate, try to negotiate compensation. Keep the animal carcasses so that the toxic substances in the sheep can be detected as evidence after forensic examination when going through legal procedures in the future. It is best to check the facts first and reserve the right to sue. After the appraisal, the legal department will know the result. Please consult a lawyer first. It may cost some money to hire a lawyer.
