About Jonathan

Jonathan Hoang

Jonathan Hoang was a 21-year-old man living with his parents and sisters in Arlington, Washington. He is on the autism spectrum and, according to his family, has the developmental capabilities of an 8 to 10 year old. He is verbal and able to hold a conversation, will respond to his name, and knows the names of his immediate family members. He is not able to navigate independently, find his way home, or live on his own. His parents have legal guardianship. He was enrolled in a transitions program through his high school at the time of his disappearance.

Jonathan was happily routine-bound. He walked a one-mile loop from his home to the school bus stop and back, three to six times daily. He never left home without his hooded jacket, which his father described as a sensory regulation tool and a security item for him. He had no history of wandering or running away.

On the night of March 30, 2025, Jonathan said goodnight to his father at 7:30 p.m. and asked to sleep in the downstairs guest room. When his mother went to wake him for school the next morning, he was gone. Left behind were his phone, wallet, ID, money, and all of his jackets. The only items missing were his iPad, his headphones, and his mother's black slip-on gardening shoes. His family believes he was coaxed out of the home by someone he had been communicating with online.

Background

What We Know

Jonathan Hoang was last seen by his father inside their Arlington home at approximately 7:30 p.m. on Sunday, March 30, 2025. He said goodnight and asked to sleep in the downstairs guest room. His mother went to wake him for school the following morning at 6:38 a.m. and discovered he was gone. The family found a lower-level door unlocked. Missing from the home were Jonathan's iPad, the wired headphones he used with it, and his mother's black slip-on gardening shoes. Everything else, including his phone, wallet, ID, money, all of his jackets, and his favorite shoes, was left behind.

Jonathan's family and advocates believe the circumstances of his disappearance indicate he was lured out, not that he wandered. He had no history of elopement or running away. His iPad, which he never took outside the home under normal circumstances, was the one item he took. His jacket, which he wore at all times and in all weather as a sensory regulation tool, was left behind. His family believes he was communicating with someone online who he trusted and who prompted him to leave during the night.

On June 23, 2025, nearly three months after he vanished, surveillance cameras in the South Juanita neighborhood of Kirkland, Washington, captured footage of a young man closely resembling Jonathan near Northeast 105th Avenue and Northeast 112th Street. His family reviewed the footage and expressed confidence that the person's mannerisms, gait, and clothing matched Jonathan. Kirkland Police confirmed receipt of the footage and coordinated with the Snohomish County Sheriff's Office. A neighborhood search was organized in the area. Jonathan has not been seen since that sighting. There have been no additional confirmed leads.

Case Timeline

How It Unfolded

March 30, 2025 — 7:30 p.m.
Jonathan Last Seen at Home
Jonathan said goodnight to his father, Thao Hoang, while Thao was on the treadmill. He asked to sleep in the downstairs guest room because the treadmill noise was bothering him. This was the last confirmed contact with Jonathan. Earlier that evening, he had returned from his daily neighborhood walk just before 7:00 p.m., which was captured on video.
March 31, 2025 — 6:38 a.m.
Jonathan Discovered Missing
Jonathan's mother went to wake him for school and found him gone. A lower-level door was found unlocked. His iPad, headphones, and his mother's gardening shoes were missing. All jackets, his phone, wallet, ID, and money remained in the home. The family called 911. The Snohomish County Sheriff's Office responded and Search and Rescue was activated.
March 31 – April 5, 2025
Six-Day Search Finds No Trace
Over 150 searchers from five county search and rescue teams, drones, a helicopter with infrared cameras, K-9 units, professional trackers, human remains detection dogs, and autism specialists participated in the search. The effort totaled over 4,000 person-hours. No physical trace of Jonathan was found and no sign of where he went was identified.
April 4, 2025
Endangered Missing Person Alert Issued
The Washington State Patrol issued an Endangered Missing Person Alert for Jonathan, five days after his disappearance. The family and autism advocacy organizations have stated the alert was delayed and only issued after the family contacted WSP and lobbied officials directly. The Major Crimes Unit of the Snohomish County Sheriff's Office also took over the case on April 4.
July 3, 2025
Reward Increased to $100,000
The total reward for information leading to Jonathan's location was increased to $100,000 after Earl Stewart, owner of Earl Stewart Toyota in Lake Park, Florida, contributed to the Crime Stoppers tip fund after reading Dateline's coverage of the case. The family had initially offered $10,000.
June 23, 2025 — 11:00 p.m.
Possible Sighting in Kirkland
Multiple home surveillance cameras in the South Juanita neighborhood of Kirkland captured footage of a young man closely matching Jonathan's description near Northeast 105th Avenue and Northeast 112th Street. His family said the mannerisms and clothing were consistent with Jonathan. Kirkland Police coordinated with SCSO. A neighborhood search was organized. Jonathan was not located.

Nine Months — Family Launches "Did You See Him?" Campaign
Nearly nine months after Jonathan's disappearance, his family canvassed downtown Arlington, distributing flyers and renewing public awareness. A coffee stand in Kirkland distributed 500 coffee sleeves printed with Jonathan's photo and case information. Jonathan's family and advocates also began supporting Washington State Senate Bill 6070, which would establish a Purple Alert system for vulnerable missing adults with developmental disabilities. No new leads have emerged. Jonathan remains missing.

Investigation

The Investigation

The Snohomish County Sheriff's Office Major Crimes Unit has led the investigation since April 4, 2025. Searches have been conducted in the areas surrounding the family home in Arlington, as well as across Oakland, San Joaquin, and Solano counties. Because Jonathan is legally an adult, investigators have faced constraints in accessing his device data without a warrant, which requires meeting evidentiary thresholds for criminal activity that have not yet been established. The family hired a private investigator to assist with the case.

The Autism Foundation filed formal complaints with the SCSO on behalf of the family regarding the handling of Jonathan's case, citing a five-day delay in issuing the EMPA, insufficient early investigation of a vulnerable adult, and lack of proactive communication with the family. The National Autism Association contacted the SCSO, the Washington Attorney General's Office, the Snohomish Prosecuting Attorney's Office, and other agencies on the family's behalf. The family's advocates have also been in contact with the FBI, the U.S. Department of Justice, and Adult Protective Services, with limited results due to jurisdictional and evidentiary constraints.

The family's website, findjonathanhoang.com, states that the lack of any confirmed sightings between March 31 and June 23 suggests Jonathan was likely not traveling independently during that period, and that he was probably being cared for by someone else. His sister, Irene Pfister, has said she believes Jonathan is alive and receiving help from someone, as he has no money, no phone, and no ID. The $100,000 reward remains available through Crime Stoppers of Puget Sound.

Help Bring Jonathan Home

If You Have Information

If you see someone matching Jonathan's description, please call 911. He will respond to his name. You can ask him "Are you Jonathan?" and he should be able to self-identify. Do not attempt to transport him yourself. Call 911 and stay with him until law enforcement arrives.

Jonathan has a large mole on his right inner forearm and two moles on the left side of his face. He sometimes walks with his hands clasped behind his back or held forward with bent arms and clenched fists. When anxious, he may rock or pace. He is not capable of independently navigating or finding his way home.

In His Name

He Is Not Forgotten

Jonathan Hoang is 21 years old. He did his daily walk. He said goodnight to his dad. He asked to sleep downstairs so the treadmill noise would not bother him. That is who Jonathan is, a young man who knows his routines and tries to take care of himself, who loves his family, who responds to his name. His father says he is somewhere between 8 and 10 years old in his developmental capabilities. He is trusting. He is not able to find his own way home.

His father, Thao, has said that every day he wakes up and wonders where Jonathan is. His sister Irene described her chest being tight and the feeling of falling without being able to catch herself. His family has not stopped. They built a website. They hired a private investigator. They canvassed streets in Arlington and Kirkland. They reached out to the FBI, the Department of Justice, the Attorney General. They made sure that Jonathan's story reached Dateline, NewsNation, and every local outlet that would listen. They are still searching.

Jonathan's case has also become a catalyst for systemic change. His disappearance and the failures in the early response have helped drive advocacy for Washington State Senate Bill 6070, which would create a Purple Alert system specifically for missing vulnerable adults with developmental disabilities. That alert would have applied to Jonathan from day one. His family is fighting so that no other family has to fight the way they have.

"I don't know if we can stand it much longer, but we have to. We need to be here when he's found, so there's really no choice."
