A Problem Shared: Has our elder been breaking the law?

The 'A Problem Shared' panel

The husband of one of our senior elders has been arrested for high-level business fraud. The local papers ran the story and pointed out that his lifestyle was well above his apparent pay grade. The insinuation is that his family must have realised that something illegal was going on. When I challenged the elder on this, she denied all knowledge of his wrongdoing. But people in the church are unconvinced by her protestations of innocence. What should I do?
