True Crime and Conspiracy--- Lead Mask Case

In 1966, The corpses of 2 men were found… Laying side by side… wearing formal suits, raincoats and home made lead sunglasses. There were no signs of a struggle and no obvious signs of death. Other items found with the men raise even more questions…. This case is still unsolved today…. And with all the unusual circumstances of course that opens up doors to conspiracies and bizarre theories…. Like UFO’s, Supernatural forces, Murder, or drug overdose. To this day we still do not know who or what killed them… forcing these men into a darkness that will last a lifetime. Did the men make contact with a UFO? Or were they the victims of a robbery gone wrong? Was this some sort of spiritual vision journey, or drug overdose? If we opt to go with the robbery explanation, then what do you make of the cryptic note, the distance traveled by the men and the fact that no signs of foul play were found? Were they part of some sort of cult Or perhaps they just committed suicide in a suicide pact…. Unfortunately we will never know
