A routine that never varied — until it did
Jonathan Hoang, 21, lived in Arlington, Washington, with his parents and two sisters. He is on the autism spectrum, and his parents hold legal guardianship. He was enrolled in a school transitions program in Arlington, learning life skills and job training, and his life ran on routine: the same one-mile neighborhood walk, up to the stop sign and back, several times a day. “He has his behavior — his pattern of life — that he pretty much sticks to very rigorously. He does the same thing every day,” his father, Thao Hoang, told NBC’s Dateline. Jonathan had never run away, never left the house alone in an unusual way, and had always said he wanted to stay home.
On the evening of Sunday, March 30, 2025, he took his last walk of the day and came home at about 7 p.m. He asked his father if he could sleep in the downstairs guest room because the treadmill was noisy, then asked if he could stay home from his program the next day because he felt unwell. His father said they would decide with his mother in the morning. At about 7:30 p.m., Jonathan said he was going to sleep. It was the last time his family saw him.
The next morning, his mother went to wake him and he was gone. Almost everything he owned was still in the house: his cell phone, his wallet, his jacket, his own shoes. The only things missing were his Wi-Fi-only iPad, a pair of wired headphones, and one of his mother’s black slip-on shoes. His phone, wallet and accounts have shown no activity since.
The search, and a detective who is still assigned
Jonathan was reported missing on March 31 and entered into the national NCIC missing-persons database the same day. The Snohomish County Sheriff’s Office Search and Rescue unit mounted a six-day search: more than 150 searchers, drones, the SnoHawk 10 helicopter, K-9 teams and man-trackers, logging over 4,000 man-hours around Arlington. Search teams returned on April 10 with human-remains-detection dogs, on April 19 with a drone, and in late April on foot and by air along the Stillaguamish River. Nothing was found. An Endangered Missing Persons Alert was issued on April 4. Detectives analyzed Jonathan’s phone and computer and worked with Apple, Google and Microsoft; there has been no electronic activity on any of his accounts, and his iPad — which has no cellular connection — cannot be tracked once it leaves home Wi-Fi.
The case was referred to the Sheriff’s Major Crimes Unit and assigned to a lead detective, who remains assigned. The Sheriff’s Office says plainly what is known and what is not: there is no evidence of criminal activity or foul play, and the investigation remains active. Jonathan’s family disagrees with parts of the early response — they say the alert came too late and the urgency too slowly — and have asked for the case to be treated as a possible crime and handled by a multi-agency task force. The Sheriff’s Office says it has not declined help from any agency and has worked the case with the Washington State Patrol’s Missing and Unidentified Persons Unit, Kirkland and Arlington police, and the FBI. Both positions are on the record; this page reports them as the family and the Sheriff’s Office state them.
The Kirkland sighting — possible, not confirmed
On the night of June 23, 2025, home surveillance cameras in the South Juanita neighborhood of Kirkland — about 45 minutes south of Arlington — recorded a young man who closely resembles Jonathan, walking at about 11 p.m. The family’s home in Arlington is on 114th Drive; the Kirkland footage was captured near NE 114th Lane, a number Jonathan may have remembered. His family believes the man in the footage is Jonathan, and moved their search to Kirkland: canvassing, flyers, asking residents to check their cameras.
The Sheriff’s Office is careful, and so is this page: detectives canvassed the area with Kirkland Police and reviewed additional surveillance, but as of their August 13, 2025 update they have not been able to positively confirm that the man in the footage is Jonathan, and there have been no confirmed sightings of him since the night he disappeared. His family believes he was lured away by someone he knew or believed he knew — someone he trusted. That is the family’s stated belief, reported by NewsNation and FOX 13 Seattle; it has not been established by investigators.
A $100,000 reward, and a law his family wants changed
A reward of up to $100,000 is offered for information leading to Jonathan’s whereabouts. It grew from an earlier Crime Stoppers of Puget Sound reward after Florida businessman Earl Stewart donated $90,000. Anonymous tips go to Crime Stoppers at 1-800-222-TIPS. On August 29–30, 2025, his family and community held a 22-hour awareness walk for his 22nd birthday, starting and ending at Juanita Beach Park in Kirkland. On March 30–31, 2026 — exactly one year after he vanished — family and community held a vigil for him in the Arlington area, covered by KIRO 7 News. His family now also campaigns for a “Purple Alert” law, so that missing adults with cognitive disabilities trigger the kind of urgent public alert that children and seniors already get. Their case site is findjonathanhoang.com.
What is not known
Where Jonathan went on the night of March 30, 2025, how he traveled, and where he is now. Whether the man filmed in Kirkland on June 23 was him. Whether anyone helped or persuaded him to leave — his family believes so; investigators say they have found no evidence of a crime. He has no phone, no money and no medication with him, and he cannot find his own way home or live on his own. Someone, somewhere, has seen him or knows something — that is the premise of the $100,000 reward, and of this page.
