Hi. I frantically need guidance. My sibling visited Mexico holiday. He tragically kicked the bucket while down there, he was just 34. It's been damnation attempting to get his body and his things back up here. My mom addressed some person at the burial service home in Mexico where they did the examination. They clutched his body for such a long time that we could never have an American post-mortem examination done nor would we be able to have a survey of his body. They likewise didn't send his own things home with him like the person said they would. Presently my mom is being told by the US department that it would be a huge load of cash and a cerebral pain to get an unfilled wallet and his glasses back. Presently I really want to know, what sort of legal counselor would I be able to recruit to sue the balls off of these individuals? How could it be that they can simply keep my sibling's things? Take cash from his wallet? Any exhortation on this sounds especially appreciated, really.
