While Dr. Roger Leir revisited the 1996 Varginha case, dubbed the "Brazilian Roswell," we looked back at some earlier alien/UFO encounters in Brazil, documented in an article by Coral Lorenzen for Fate Magazine in September '71.
One encounter she writes about took place in August of '67 at a farm where Inacio de Souza and his wife witnessed a "strange basin-shaped object approximately 115 ft. in diameter," and three hairless child-like creatures near the craft. Moments after Inacio pointed a rifle at the beings, he was hit with a "jet of green light erupting from the craft." He immediately became ill, and within two months was dead. Though he had been diagnosed with leukemia, it was suspected he had radiation poisoning, Lorenzen writes.
In a case from Feb. 1969, another basin-shaped object was seen, giving off a bluish light in Pirassununga. Tiago Machado reportedly tracked the object with binoculars and found where the disc had landed. He said two yellow-complexioned figures emerged, about 3 ft. 8 inches in height, and wearing silver clothes. Their noses seemed "squashed," and a tube pointing downward from their chins "seemed to project harsh guttural sounds." Machado tossed a pack of cigarettes toward the beings, and one of them made the pack rise in the air by placing his hand above it, he claimed. Before leaving they pointed a contraption at Machado that sent a "bluish-red flash" into his legs. Subsequently, a doctor described Machado as suffering from something like "electric shock burns," but he fully recovered in a few days.
