If the person entered the jar alive, they would have brought with them whatever they were carrying — in this case, two knives and a belt.

The presence of these objects does not require any special explanation beyond “he had them with him.”

What the hiding hypothesis does not yet explain:

Whether the fire killed him or whether he was already injured.

The cause of death is not established.

Smoke inhalation and fire are the obvious candidates, but without forensic analysis of the skeletal remains — looking for evidence of pre-mortem injuries, analysis of bone changes that might indicate fire exposure while alive versus after death — these possibilities cannot be distinguished.

Whether the fire was set by attackers or began some other way.
