It looks like someone is covering their tracks and is freaked the fuck out. Recently, thanks to advances in forensics, there is an order to exhume the body of Jon. There are experts who worked on the original case that had made remarks and pointed figures at suspects and were most certainly right about their educated judgement calls. However the lack of forensic evidence lead to a cold case.

THESE ARE EXPERTS THAT WOULD HAVE TESTIFIED AND BACKED UP WHATEVER NEW EVIDENCE IS TO BE FOUND DURING THE NEW INVESTIGATION, AND NOW THEY ARE DEAD. Someone is scared and I will bet money that someone low level will be thrown under the bus when all of this is over.
