Two Men Died in Strange Circumstances

In Rio de Janeiro, Brazil in 1966, two men died in strange circumstances, which have yet to be explained. It is unclear whether the men were murdered or if it was suicide. There were several objects found around the men and the case has been called the Lead Masks Case.Two electronic technicians, Manoel Pereira da Cruz and Miguel José Viana, told friends and family they were going to buy some supplies for work and buy a car. They apparently already had the money on them.They stopped off to buy a bottle of water and a coat. They apparently seemed to be in a hurry and kept looking at their watches.

Their bodies were found a few days later. The police determined the last moments the men were alive and found some items that represented their last moments alive. They were both dressed in suits and they had on waterproof coats. They wore lead eye masks with no holes such as one would wear to protect form radiation. They also found an empty water bottle, a notebook, and two towels. The money they were supposed to be carrying for the purchase of a car wasn’t found.The notebook contained these words in Portuguese “16:30 be at agreed place, 18:30 swallow capsules, after effect protect metals wait for mask signal.”The toxicology didn't offer any concrete results. It’s still unknown if they took the capsules or not. It appears they were waiting for someone to tell them to put on their masks.
