[@Huckleberry1911] - Perhaps he might have found someone who knows something about his brother, who needed to meet in person - and when he wanted to leave to go find them, his brother found out as well and organised for a framing in town - while he looked for the snitch. Maybe one of Diether's clients killed another, and is blaming him for manipulating them into doing it - when actually they were paid to do it by his brother. I think his brother would not have sent him to this town if he did not have contacts there.
