Man found dead in a panic room. it appears he was killed by an explosive that originated inside his body, it is unclear if it was in his GI tract or implanted subdermally.

The man was originally a missing persons report, filed when he did not attend a scheduled meeting with the board of directors for his company (manufacture and distribution of paper goods); prior to that meeting it appears the man had cleared his schedule for a two-week period, and died about halfway through that period.

the panic room is an effective faraday cage, no sign of forced entry, food stores and waste products indicate he had been locked in the room for a little more than a week at the time of his death, consistent with him entering the room just after his last scheduled meeting.

There are multiple notebooks in the room that it appears he was writing in during his time in his room. They have been rendered mostly unreadable by the blood splatter, and what is legible is filled with some form of cipher or code. Our linguists have had no success as this time.
