After all, if they couldn't pin everything on the boar despite having proof of it killing Jake, it was unlikely that they would be able to pin the murder on someone else. They doubt that they will be able to find evidence to catch the real murderer.
But their boss insisted, so they continued to investigate. The place they went next was Jake's house to speak with his widow.
His immediate family was currently in mourning. So when they got there, they couldn't speak with the wife immediately.
It would be inappropriate to interrupt the mourning rites of a widow. It is actually more than inappropriate.
It would be disrespectful to do the widow and the deceased family to interrupt the mourning rites. Seeing as the widow and deceased family are the Dyson family, they could actually lose their heads if they are not careful.
They don't want to lose their life over a dead man and some merits, so they decided to be careful. The best way to be careful is to be gentle and slow.
