On February 24, 1978, five men from Yuba City, California, drove to Chico to watch a college basketball game. They stopped for snacks afterward, then appeared to head home as planned. But three days later, their 1969 Mercury Montego was found abandoned on a remote mountain road deep in the Plumas National Forest, nearly 50 miles from the route home, with fuel still in the tank. The men were nowhere to be found. Months later, four would be discovered dead in the wilderness, while the fifth, Gary Mathias, would disappear without a trace. Nearly everything about the case raises the same question: Why did five men leave a working car and walk into the mountains?
They Went To A Basketball Game And Never Came Home
The five men—Jack Madruga, Bill Sterling, Ted Weiher, Jackie Huett and Gary Mathias—were between 24 and 32 years old. They knew one another through basketball and programs that helped people with mild developmental disabilities or psychiatric conditions, and they lived with their families while maintaining enough independence to travel locally on their own. Their families knew them well, and none was known for simply disappearing overnight.
That Friday evening, they drove Madruga’s Mercury Montego about 50 miles to Chico to watch a college basketball game between Chico State and UC Davis. After the game, they stopped at a convenience store and bought snacks and drinks for the drive home. Witnesses reported seeing them leave in the direction of Yuba City, making what happened next even harder to explain.
The men were also expected to play in a Special Olympics basketball tournament the following day. When they failed to come home and then failed to show up for the tournament, their families immediately became concerned. The search for the five began the next morning.

Their Car Was Found In The Wrong Place
On February 27, a U.S. Forest Service ranger came across Madruga’s Mercury Montego stuck in a snowbank on a remote road in the Plumas National Forest. The location was the first major mystery: the car was roughly 50 miles away from the normal route between Chico and Yuba City, deep in a mountainous area where the men had no obvious reason to be.
The car did not appear to have been abandoned because it had run out of fuel. It still contained roughly a quarter tank of gas, and the keys were reportedly missing. There were also maps in the glove compartment, yet investigators found little evidence explaining why the group had traveled so far from home.
Even more puzzling was the snowbank itself. Investigators believed the five men might have been able to move the vehicle, but instead they left it behind and apparently continued on foot into the mountains. The surrounding area was already covered in snow, and winter conditions would soon make the search far more difficult.
For the families, the central mystery had suddenly become painfully simple: why would five men voluntarily leave a usable car on a freezing mountain road?
One Witness Reported Something Strange
Investigators later heard from Joseph Schons, a man who had also become stranded in the same remote area that night. Schons said that around 11:30 p.m., he saw headlights and then noticed several men getting out of a vehicle, along with a woman carrying a baby. He called for help, but according to his account, the group stopped talking and moved away. He later reported seeing flashlight beams farther up the road.
Schons’ account became one of the most discussed elements of the case, but it has never been independently confirmed. Investigators found no evidence establishing that a woman and baby had actually been with the five men, and questions about Schons’ condition that night complicated how his observations should be interpreted. He had reportedly suffered a heart attack and was in distress while stranded in the snow.
That means the witness account can be treated as a lead, not an established explanation. It has fueled theories of foul play for decades, but the evidence does not prove that another group was involved. The mountains offered no immediate answer.
The First Body Was Found Months Later
Search crews were initially limited by severe winter weather. The case remained unresolved until the snow began to melt in the spring.
On June 4, nearly four months after the disappearance, people exploring the forest found a Forest Service trailer about 20 miles from where the Mercury had been abandoned. Inside was the body of Ted Weiher, lying on a bed and wrapped in several sheets. He had lost a tremendous amount of weight, suffered severe frostbite and appeared to have survived underground in the wilderness for a considerable period before dying.
What investigators found around Weiher made the scene even more disturbing.
The trailer contained food, while nearby sheds held fuel, matches and propane. Yet the fireplace had not been used, and there was no clear evidence that the available food or heating supplies had been used in the way investigators would expect someone desperately trying to survive.
Weiher had apparently reached a place that could have offered at least some protection from the elements. But somehow, he still died there.
Then Three More Bodies Appeared
The day after Weiher was discovered, the remains of Jack Madruga and Bill Sterling were found several miles away in the forest. A short time later, investigators discovered Jackie Huett’s shoes, spine and skull in another area nearby. Their remains were scattered across roughly a 20-mile radius from the abandoned car.
The findings established that the men had traveled a considerable distance into the mountains after leaving the vehicle. What remained unclear was whether they had stayed together, when they separated or whether all four had ever reached the Forest Service trailer. And there was still one person missing. Gary Mathias had vanished completely.
Gary Mathias Left Behind The Biggest Mystery
Mathias was 25 when the group disappeared. His shoes or sneakers were reportedly found in the Forest Service trailer, suggesting that he may have reached the location at some point, but no remains were ever recovered. His family searched for years, and his disappearance became the most enduring mystery within the larger case.
That missing body changed the nature of the case. Four men had died after somehow entering a remote wilderness area in winter, but there was no final evidence showing what happened to Mathias. Without a body, investigators could not establish whether he died somewhere else in the mountains, left the area or became a victim of foul play.
His father once explained why the absence of even one small piece of evidence was so difficult to accept, noting that what he wanted most to find were Mathias’ glasses. The fact that even those were never recovered became symbolic of how little the family ultimately learned.
Five men had entered the mountains. Only four ever came back in any physical form.
No Theory Has Explained Everything
Over the years, investigators and amateur researchers have proposed numerous explanations. Some theories suggest the men became confused, frightened or disoriented and entered the mountains for reasons that made sense to them at the time. Others have suggested they encountered another person or group after leaving the highway. Families of the missing men have long believed that something more serious happened.
But there is an important distinction between what is possible and what the evidence proves.
There is no established explanation for why the men traveled so far off course. There is no confirmed evidence proving that another person forced them into the wilderness, and there is no definitive explanation for why supplies inside the trailer were not used effectively. Investigators were left with physical evidence, conflicting possibilities and a missing man whose remains were never found.
A California Department of Justice investigator summarized the frustration of the case with a simple observation: there were countless leads, but no explanation that tied everything together.
That is why the Yuba County Five remains so compelling. The mystery is not that nobody has invented a theory. It is that none of the theories completely fits the evidence.
The Car May Still Be The Most Important Clue
Almost every theory eventually leads back to the Mercury Montego.
Five men left a basketball game in the ordinary way. They bought food and drinks. They were expected home that night. Then, somehow, their car ended up on a remote mountain road far outside their normal route.
The vehicle was not empty in the sense of having no resources. It still had fuel. Yet the men left it behind and continued into a winter landscape where survival became increasingly difficult. Months later, their bodies were found scattered across the mountains, with one man still missing.
That sequence is what makes the case so difficult to dismiss as a simple accident.
There may be an ordinary explanation that has never been discovered. There may have been a chain of mistakes, confusion and poor decisions that turned a wrong turn into a tragedy. Or something happened between the basketball game and the mountain road that investigators never managed to reconstruct.
Almost 50 years later, the most important question remains the same. What made five men leave the car?
Five men left a basketball game in California on February 24, 1978 and never returned home. Their Mercury Montego was found three days later on a remote mountain road nearly 50 miles off their expected route, with fuel still inside. Months later, four men were found dead in the surrounding wilderness, while Gary Mathias was never found. A Forest Service trailer contained food and heating supplies that apparently went largely unused, adding to the mystery. Investigators received countless leads but never established what drove the men into the mountains. The case remains unsolved, with the abandoned car still at the center of the mystery.
P.S. This article is based primarily on All That’s Interesting’s reconstruction of the Yuba County Five case, supplemented with later evidence-focused research and historical summaries. The disappearance occurred in February 1978; four bodies were recovered that June, while Gary Mathias has never been found. Claims about foul play, the mysterious woman and baby, and what caused the men to leave the car remain unproven. Sources: https://allthatsinteresting.com/yuba-county-five
