9 After attending a college basketball game with his four friends, Gary Mathias was never seen again. His four friends were found decaying in and around a remote cabin 20 miles away from their car. They died from starvation and hypothermia, despite an ample supply of food and heating materials.

The five boys, Bill Sterling, Jack Huett, Ted Weiher, Jack Madruga, and Gary Mathias, all hailing from Yuba, California, were between the ages of 24 and 32 years old. The five of them were under medication for mild intellectual disabilities or psychiatric conditions.

On February 25, 1978, they were reported missing when they didn’t return home from a basketball game at California State University, Chico, which was 50 miles north of Yuba. After several days of searching, the police found the car abandoned up above the snowline far away from their homes. The authorities found no real reason why the group headed east from Chico instead of heading back south toward their homes. The last person to see them alive was a clerk at a convenience store they stopped at after the game.

In June, months after the incident, four of the bodies were found in and near an abandoned trailer park, which was 20 miles from their car. Among the four bodies, only Ted Weiher was found in the trailer, and he seemed to have lived there for at least three months before he starved to death despite having an ample food supply. His shoes were missing, and his feet were frostbitten. The other three bodies had only the bone remnants left by scavenging animals. Gary Mathias’s body, however, was never found. His shoes were found nearby, suggesting that he had been alive for days after they were last seen.

Gary is still missing to this day. Nobody knows what happened to him. Their parents have stated that it was unlikely that the five young men would have ventured out spontaneously as they did because they tended to stick to their habits. They believed that there was some mysterious force that led them there. The whole situation suggests foul play, but since there was little to no evidence, the case is still unsolved. (source)

10 In the Metcalf Sniper Attack, a team of gunmen damaged 17 transformers in the Metcalf Transmission Substation.

In the early hours of April 16, 2013, the Pacific Gas and Electric Company’s Metcalf Transmission Substation in Coyote, California, was attacked. The attack began around 1 a.m. when someone snuck into an underground vault and cut the fiber-optic AT&T telephone cables. Shortly after, snipers opened fire on a nearby electrical substation. The assault lasted for 19 minutes and damaged 17 transformers costing $15 million.

The attack was called “the most significant incident of domestic terrorism involving the grid that has ever occurred” by the then-chairman of the Federal Energy Regulatory Commission, Jon Wellinghoff. An FBI spokesman has said that the agency does not believe a terrorist organization was responsible. The case is still unsolved, and they have not found any suspects or a motive behind the attack. (source)
