An explorer was found dead in his tent in the Sahara Desert, surrounded by scattered gear. The official report listed severe heatstroke. Detective Harper looked at the scene photo showing the zipper of the tent fully sealed from the inside and a heavy winter parka draped over the explorer's bones. Harper reopened the case as a homicide. Why?
Nobody suffering from severe heatstroke in the desert would voluntarily zip themselves inside a tent and put on a heavy winter parka.
Heatstroke victims experience extreme overheating and delirium, causing them to strip off clothing, not bundle up in winter gear inside a closed tent.
