The Vanished Podcast

Twenty-one-year-old Jonathan Hoang disappeared from his home in Arlington, Washington, sometime between the evening of Sunday, March 30, and the early morning hours of Monday, March 31, 2025.

On the night of March 30, Jonathan asked his father if he could sleep in the downstairs guest room, saying the sound of the treadmill was bothering him. A short while later, he returned to say he wasn’t feeling well and asked to stay home from school the next day. His father suggested waiting to see how he felt in the morning. Around 8 PM, Jonathan told his dad he was heading to bed downstairs. It was a small deviation from routine that was odd, but not alarming. The next morning, Jonathan’s mother went to wake him for school and found that Jonathan was gone.

Jonathan is on the autism spectrum and lived a quiet, structured life. He spent most of his time at home with his family or at school, where he was enrolled in a transitional program for young adults designed to help them build independent living skills and prepare for work.

Jonathan was a creature of habit, and his routines brought him comfort. One of those routines was walking the same path through the neighborhood, always wearing the same jacket with a hood, even on the hottest days. That jacket became a part of how neighbors recognized him. But on the morning his mother discovered he was missing, the jacket was still inside the house. The items missing along with him were his iPad and earbuds. He left behind his phone, his beloved jacket, and every indication of routine.

His family called the police immediately. Search and rescue teams canvassed the area, and neighbors helped in the effort. Despite extensive early searches, no sign of Jonathan was ever found. Months have passed since Jonathan disappeared, and his family continues to search and to fight for answers.

You can follow the family’s search efforts on social media at Help Us Find Jonathan Hoang – Endangered & Missing Person on Facebook.

There is currently a $100,000 reward for information. If you see Jonathan, please call 911 immediately.

If you have any information about the disappearance of Jonathan Hoang, please contact the Snohomish County Sheriff’s Office at 425-388-3393 or Crime Stoppers of Puget Sound at 1-800-222-TIPS (8477) or through the P3 Tips App, where tips may remain anonymous.

Jonathan Hoang Part 1: When the Pattern Broke

21-year-old Jessica Foster, known to those close to her as Jessie, disappeared from Las Vegas, Nevada in late March of 2006. Jessie was far from her home in Canada, and her family didn't really know the ins and outs of Jessie's daily life in Sin City. They had last seen Jessie in late 2005 when she returned home to visit her loved ones for the holidays. She didn't seem quite like herself, but her family couldn't quite pinpoint the changes in her demeanor. Her once-vibrant spirit seemed to have faded, raising quiet concerns. In March, her family lost all communication with her. It was later revealed that her journey to Las Vegas was far darker than anyone had known. Nearly 19 years later, Jessie's family continues to search for the truth behind her disappearance, hoping to uncover the story of what happened to their beloved daughter and sister.

If you have any information regarding the disappearance of Jessie Foster, please contact the North Las Vegas Police Department at (702) 633-9111 or the Crime Stoppers Tip Line at (702) 385-5555.

Nineteen-year-old Anastasia Ferreira, affectionately known as "Stasia" by those closest to her, was the kind of person who couldn't help but be noticed. Though Anastasia stood just around 4'11", her personality loomed large, making her impossible to overlook. She was a vibrant force of nature to her family: a ball of energy with a heart big enough to embrace everyone she encountered. As a child, Anastasia was a daredevil, fearlessly climbing swing sets to the highest bar and filming herself spinning on ceiling fans. Her loved ones remember her as adventurous and bold, someone who constantly pushed boundaries and wasn't afraid to stand up for herself. Yet, beneath that fearless exterior was a young woman shaped by early childhood trauma and a relentless desire for stability in a chaotic world.

In mid-March 2023, Stasia vanished without a trace from Albuquerque, New Mexico. The details surrounding her disappearance are as perplexing as they are devastating. One moment, Anastasia was engaging with friends and posting on social media; the next, she was gone, leaving her family in a state of agony, desperately searching for answers in the face of her sudden and unexplained absence.

Upon learning that Anastasia was missing, her family began searching the streets of Albuquerque for clues about what may have happened to her. They began hearing a flurry of stories that seemed conflicting. Nearly two years later, they are still sifting through the puzzle pieces they have gathered, hoping that the truth will come into focus.

If you have any information regarding the disappearance of Anastasia Ferreira, please call the Albuquerque Police Department at 505-242-2677.

On April 11, 1981, 15-year-old Barbara Cotton vanished without a trace from Williston, North Dakota. Her mother, Louise, immediately began contacting Barbara’s friends, hoping to learn to find her. When no one had seen her, Louise reported her daughter missing to the Williston Police Department and passed along any tips she received. However, as the weeks and months passed, there was no sign of Barbara, and the case went cold. To those closest to her, it seemed as though little was being done to locate her, fueling their suspicions that the investigation was stagnant. The prevailing assumption at the time was that Barbara may have run away, a common conclusion for missing teens in that era.

However, decades later, the case remains unsolved, and there is now a renewed push to uncover the truth behind Barbara Cotton’s disappearance. Many questions remain unanswered, and the search for answers continues.

If you have any information about Barbara Cotton’s disappearance, please contact the Williston Police Department at 701-577-1212.

Isaac Seidel, a 36-year-old man from Blain, Pennsylvania, disappeared on September 12, 2021. His loved ones grew concerned when Isaac missed several days of work, prompting them to visit his home. There, they discovered a chilling scene: Isaac, who lived alone, was gone, but his bicycle, backpack, and phone were missing. Everything else seemed untouched, including chicken thawing in the sink, suggesting he had planned to return home to cook dinner.

Initially, Isaac’s family feared he might have suffered a tragic accident, and they began combing the roads near his home, searching ditches and ravines, but found no trace of him. Now, several years later, they continue to search for answers, holding onto hope that they will uncover the truth behind his disappearance.

Yesterday, we shared the first part of Isaac Seidel's story, providing insight into his life and the events leading up to his disappearance. You learned that Isaac vanished along with his bike, phone, and backpack, leaving behind everything else at his home. Isaac hadn't mentioned to anyone that he had plans to go anywhere. In fact, it appeared that Isaac was simply going about his usual Sunday routine. He had chicken thawing, something he regularly did to prep meals for the week. It seemed he set out for a bike ride, intending to return in time for dinner. But something happened to Isaac, and several years later, his whereabouts remain unknown.

In April 2019, Katherine Hammontre Sundquist embarked on a hike with friends and her beloved dog, Tootsie, in a national park near San Felipe, Baja California, Mexico. Their destination was a picturesque waterfall. Before the hike, Katherine had injured her foot, and not long after beginning the trek, she informed her friends that her foot was hurting. She decided to stay back at the first set of pools with Tootsie while the others continued on to the waterfall. It would take the group approximately 50 minutes to reach the waterfall and return to where Katherine was waiting. However, by the time the group returned, both Kat and Tootsie had vanished. Despite extensive searches of the area, no trace of either Katherine or Tootsie has ever been found. As news of Kat’s disappearance spread, rumors began to circulate within the community of San Felipe. People pointed fingers in various directions, but more than five years later, the mystery of what happened to Katherine Hammontre Sundquist remains unsolved.

In early August 2022, 24-year-old Andi Wagner mysteriously vanished from Evansville, Indiana. On August 6th, she briefly visited her grandparents' house before heading out. Andi's destination was unknown. Later, she was with a man she knew. He claimed Andi left his home either late on the evening of the 6th or in the early morning hours of the 7th. Oddly, evidence showed that the phone Andi was using continued to ping at that location until the afternoon of the 7th. 

In the wake of her disappearance, conflicting stories began to emerge about who Andi had been with and when, muddying the details of what transpired when Andi vanished. Despite extensive search efforts, no trace of Andi Wagner has ever been found.

For a time, Andi's case drew national attention, but it also attracted the involvement of individuals with questionable motives, shifting focus away from the search for her. Over time, her disappearance has become almost mythical in local lore, amplifying rumors and speculation. Nearly two and a half years later, Andi's loved ones continue their tireless pursuit of answers, determined to uncover the truth behind her sudden and unexplained disappearance.

If you have any information regarding the disappearance of Andi Wagner please call the Evansville Police Department at 812-436-7896.

On June 28, 2024, Darrel Johnson left his home in Phoenix, Arizona, and traveled to Conchas Lake State Park in New Mexico to join a group of over 30 people camping there for a birthday celebration. The group arrived and settled into their campsite. According to those camping with him, Darrel was last seen around 11 PM that night.

However, a fellow camper, who was not part of Darrel's group, reported seeing him after midnight. This camper recalled that the individual he believed was Darrel asked to borrow a flashlight and was then seen walking back toward his campsite with it in hand. That was the last sighting of Darrel Johnson. What happened to him after that moment remains a mystery.

In the months that followed, Darrel's family launched an intensive search, determined to find any clue that would lead them to him. Despite their relentless efforts, not a single trace of Darrel has been uncovered.

If you have any information regarding the disappearance of Darrel Johnson, please call the New Mexico State Police at 505-425-6771.

Darrel Johnson Part 1: Where the Trail Ends

In this final installment of Amos Mortier's story, Vanished producer Nathan Comp gives us a peek into the evidence he says points to someone other than Big Jake Stadfeld, who police have eyed as their main suspect for the last 12 years. Former Det. Shannan Morgan, who headed the investigation into Amos's disappearance for nearly eight years, gives her reasons for fingering Stadfeld over all these years, despite the fact that nothing came from her probe. In this jaw-dropping finale to our four-part series on Amos Mortier's befuddling disappearance, you have a front-row seat to a missing person investigation run amok.
