Is the big end of the rod burnt? Black in color? If so the friction between the connecting rod without a bearing insert and the bearing journal heated up the rod bolt causing it to fatigue. The heated bolt will stretch and lose its preload. Eventually breaking, or in some case the nut falling off.
The tin foil was a bearing. When a bearing fails and the clearance opens up, the bearings get hammered. looks to me like the owner of this engine ignored the knock or had his stereo up.
