jamestown,ask for justice.

my character was murdered,though I raided a claim,but no one lives there any more.But the guy I treated as my friends murdered me,and they raided my claim.Yesterday,I built a new character wants to talk with him.the man in his claim invited me in,and said he had msg him.But the man killed me without saying nothing after that,I even hadn't talked to the guy.How can they murder a man invited into their claim?where's the guest's right?
