Teen Couple Vanished in Yosemite – 7 Years Later the Boy’s SKULL Was Found Nailed to a Tree…
In the serene beauty of Yosemite National Park, where towering cliffs and lush forests create an idyllic backdrop, a chilling mystery unfolded that would haunt the region for years. It began on August 3, 2016, when the abandoned car of two young lovers, Eliza Morrison and Owen Griffiths, was discovered in a parking lot near the Tioga Road Trail. What followed was a search that would span years, culminating in a gruesome discovery that would reveal a dark underbelly of crime hidden within the park’s wilderness.
The Disappearance

Eliza Morrison, an 18-year-old from San Francisco, and her boyfriend, 19-year-old Owen Griffiths, set out for a week-long hike in Yosemite, excited for their first adventure together without parental supervision. They were inseparable, known among their friends for their deep bond and adventurous spirit. On July 27, 2016, they left their home, eager to explore the beauty of the Sierra Nevada mountains.
The couple’s journey began with a stop at a gas station in Oakhurst, where security footage captured them filling up their white Ford Escort and purchasing supplies—water, candy bars, and batteries for their flashlight. They signed into the visitor log at the park, noting their intended route to Grizzly Valley and an estimated return date of August 5. Initially, their social media updates showcased stunning views and joyful moments, but as the days passed, their posts ceased.
When they failed to return as scheduled, their families raised the alarm. On August 6, park rangers discovered their locked car in the parking lot, containing spare clothes, a phone charger, and several bottles of water. This indicated that the couple had planned to return. The search operation commenced immediately, involving helicopters, dog teams, and hundreds of volunteers.
The Search Operation
For over a week, search teams combed the rugged terrain of Yosemite, focusing on the area where the couple was last seen. The search was exhaustive, utilizing helicopters equipped with thermal imaging, but yielded no signs of the missing hikers. On August 18, after 11 days of searching, a volunteer stumbled upon a scrap of Eliza’s red sweater caught on a thorny branch deep in the forest. This discovery, over three kilometers away from any official trail, raised more questions than answers.
As the search continued, the official narrative suggested that the couple had become lost, possibly succumbing to exhaustion or a sudden change in weather. However, Eliza’s father, Mark Morrison, refused to accept this explanation. He believed that something more sinister had occurred. “My daughter couldn’t have just disappeared. She left a trail, and someone erased it,” he stated, demanding that the search continue.
Despite the extensive efforts, hope began to fade. The case was officially listed as a disappearance, and the families were left in limbo, grappling with the uncertainty of their loved ones’ fates. For years, the story of Eliza and Owen became a haunting tale whispered among locals and tourists alike, a reminder of the dangers that lurked in the wilderness.
A Shocking Discovery
Seven years later, on September 9, 2023, a group of botanists from the University of California set out on an expedition to Grizzly Valley. Their objective was to document rare moss populations, but what they found would send shockwaves through the community. As they navigated through the dense forest, they stumbled upon an old pine tree with a human skull nailed to its trunk by a large, handmade nail.
The discovery was grotesque and shocking. The skull was identified as belonging to Owen Griffiths, confirming the worst fears of both families. Alongside the skull, forensic experts found additional bones arranged in a circle, suggesting a ritualistic nature to the act. The news spread quickly, reigniting interest in the long-cold case and raising new questions about the circumstances surrounding the couple’s disappearance.
The Investigation Reopens
Detective Sophia Reyes, a newly assigned investigator with a background in handling complex cases, took charge of the reopened investigation. She quickly recognized that this was no ordinary murder case. The skull’s placement and the arrangement of the bones hinted at a deliberate act, possibly linked to a larger, more sinister operation within the park.
As Reyes delved into the details of the case, she discovered a series of reports documenting strange occurrences in Yosemite over the years—unexplained lights in the forest, sightings of mysterious figures, and even reports of symbols carved into trees. These incidents, previously dismissed as folklore or the product of overactive imaginations, now took on a new significance.
Reyes consulted with local experts, including Arthur Lawrence, a historian specializing in Native American legends. Lawrence recounted the myth of the Avanichi tribe, who believed that excessive love could disrupt the balance of nature. To restore harmony, they performed rituals involving the sacrifice of young couples. The chilling parallels between this ancient legend and the current case began to take shape.
The Search for the Truth
With the evidence mounting, Reyes organized a second search of the area where Owen’s skull was found. Accompanied by forensic experts and rangers familiar with the terrain, the team set out to uncover more clues. Their expedition led them to an abandoned cabin, previously used as a geological station during the gold rush. Inside, they found remnants of a life lived in secrecy—cans of food, a makeshift sleeping area, and a disturbing collection of newspaper clippings about missing persons in Yosemite, including Eliza and Owen.
Among the items was a diary belonging to a man named Daniel Cross, who had become obsessed with the legends of the park after losing his daughter in a tragic accident. His writings detailed a twisted belief system that echoed the myths of the Avanichi, suggesting that he and an accomplice had been acting out these rituals in the mountains.
The Arrest
As Reyes pieced together the evidence, she identified Cross as a key suspect. His connection to the disappearances and the ritualistic nature of the murders painted a clear picture of a man driven by grief and madness. With the support of local law enforcement, Reyes obtained an arrest warrant for Cross, who had been living in the shadows of the park for years.
The operation to apprehend him was swift and decisive. Cross was found hiding in a remote area of the park, surrounded by remnants of his twisted rituals. During his interrogation, he confessed to his involvement in the deaths of Eliza and Owen, claiming he believed he was preserving their love for eternity.
Conclusion: A Haunting Legacy
The case of Eliza Morrison and Owen Griffiths serves as a haunting reminder of the darkness that can lurk beneath the surface of nature’s beauty. The discovery of Owen’s skull and the subsequent investigation revealed not only a tragic end for two young lovers but also the existence of a disturbed individual who had twisted ancient myths into a horrific reality.
As the community grapples with the aftermath of this revelation, the legend of the couple who disappeared in Yosemite continues to resonate. Families and friends are left to mourn their loss, while the park remains a place of both beauty and danger—a landscape that holds secrets and stories waiting to be uncovered.
In the end, the mountains of Yosemite, with their silent grandeur, bear witness to the tragedies that unfold within their depths, reminding us that even in the most breathtaking places, darkness can thrive.
