Crystal skulls, found already in different parts of the planet, most often look like human skulls and are of appropriate size, and they are most often made of quartz (rock crystal).

It is said that they were first created by the Maya, but the accuracy of the work done calls this claim into question. If we take into account the tools used by the Maya, it would take hundreds of years or ultra-modern technology, which even today not every country has.

On September 16, 1994, 34-year-old musician Donald De Villa and his wife Stephanie celebrated the baptism of their youngest 2-year-old daughter Donatella. In addition to the daughter in the family grew a 3-year-old baby boy Donald. After the celebration, the entire family disappeared without a trace.

Stephanie's mother, Gilbert, lived near Paris. For a week now, she had not received any information from her daughter.

She called the police and they sent two police cars to the house where her daughter lived with her husband and children, but no one was there. There were children's toys lying around in the yard. It was very strange: the daughter liked order.

This strange story took place in 1977 and is truly extraordinary. February 25, Moscow, Domodedovo airport. A report was received from one of the airliners about the death of a person on board and a request for an unscheduled landing. Permission was granted and soon the aircraft landed. Airfield services and medics rushed to it. To their surprise, a young stewardess had died. The doctors examined the deceased and asked to call the police - the girl had obvious signs of cyanide poisoning. The investigative-operative group that arrived confirmed the conclusions of the doctors. But who could have poisoned the stewardess at an altitude of 10,000 meters? Or maybe she herself decided to say goodbye to life? Law enforcers had to figure it out.

On February 24, 1978, at 10 p.m., as a basketball game ended at California State University, Chico, five young men got into a white and turquoise 1969 Mercury Montego and drove out of the parking lot. They were fans of the winning team.

The guys stopped outside a Behr's Market store, slightly annoying the clerk (who was trying to close the store), and bought one Hostess cherry pie, a Langendorf lemon pie, a Snickers bar, a Marathon bar, two Pepsi shots, and a liter and a half of milk. They then left the store, got into their car, drove south and disappeared.

The boys were waiting at home. They had an important basketball game the next day.
