THE LEAD MASKS DEATHS MYSTERY
The mystery began on August 21st, when the bodies of two men were found in a hilltop clearing near Niteroi, Brazil. (Niteroi is across the bay from Rio de Janeiro.) Two lead half-masks, for covering the upper half of the face, and strange, partially coded notes were found beside the bodies.
The two men were identified as Manuel Pereira di Cruz, aged 32, and Miguel Jose Viana, aged 34. They were both radio and television technicians. According to an autopsy report they died from stoppage of the heart. There was no apparent cause of this. The men had been dead for about four days when they were found.
A mathematician reported that part of the notes contained only the ohm equation (dealing with the strength of electric current) and the rest was unintelligible.
A number of people came forward during the investigation with reports of an oval, orange coloured object hovering over the top of the hill. One woman reported seeing the object at the time the men went up the hillside. The affair was investigated by local detectives and experts from Rio de Janeiro with the help of troops and the Brazilian Information Service. A weird array of theories was considered including murder, suicide, smuggling, sorcery, spiritualism, attempts to contact the Martians, atmospheric electricity and radio waves. A man who reported that the men had been trying to contact the planet Mars was held by police for questioning. This man was said to have exercised a powerful influence over the dead men and to have owed them money. According to one report, a man and a woman were arrested in connection with the case. The men were said to have had a great deal of money with them when they went up the hillside. The notes found on their bodies indicated that they had "taken orange capsules" and were "waiting for the promised sign".
When detectives searched Manuel Viana's workshop they found lead from which the masks were apparently made, and a book on scientific spiritualism, with marked passages referring to masks and intense rays of light.
The police eventually called off their investigations, having failed to solve the mystery. Detective Idovan Ferreira, who led the investigations said: "I have no doubt they died of an experiment with psychic forces, for which they were ill-prepared and which turned out to be fatal."
