Suspected Kidnapping Targeting Crypto Wealthy Family: FBI Joins Search for Missing 70-Year-Old in California

The disappearance of a 74-year-old man from a quiet residential neighborhood in Rancho Cucamonga, California, has escalated into a major federal investigation. As of April 27, 2026, the Federal Bureau of Investigation (FBI) is concentrating its investigative resources to locate Naiping Hou, who has been missing for over a year.

This case has emerged as a new security threat in the digital finance era, as possibilities of a planned crime targeting the family's cryptocurrency assets have been raised beyond a simple disappearance. The bereaved family believes Naiping Hou's safety was compromised due to the digital assets that symbolize the family's professional success.

Wen Hou, the son of the missing person and a well-known cryptocurrency investor, has been appealing for federal intervention, claiming his father was targeted by a criminal organization. Consequently, the FBI recently classified this case as a high-risk crime and expanded the scope of the investigation.

The FBI began its full-scale investigation into Naiping Hou's disappearance in April 2026. This intervention was confirmed as part of a broad resource allocation plan by federal authorities to combat violent crime and criminal organizations.

We believe our family's success in cryptocurrency investment put our father in danger. The criminals used deceptive methods and are very dangerous individuals.

This investigation has been included as a key task in 'Operation Not Forgotten 2026,' announced by the Department of Justice. This is an initiative operating under the FBI's 'Operation Steadfast Promise,' aimed at responding to violent crime threats and improving public safety.

Circumstances of Disappearance and Connection to Cryptocurrency Assets

Naiping Hou has been missing for over a year since he was last seen on March 18, 2025. The local San Bernardino County Sheriff's Department has been conducting an initial investigation since May 2025, but cooperation with federal authorities was established as evidence emerged that complex financial crimes were intertwined behind the case.

• Name: Naiping Hou
• Age: 74 (at the time of disappearance)
• Last Seen: March 18, 2025
• Residence: Rancho Cucamonga, California

During the investigation, it was revealed that approximately $1 million (about 1.3 billion KRW) was withdrawn from Hou's bank account. This was adopted as evidence strongly supporting the possibility of a kidnapping motivated by financial gain rather than a simple disappearance. Authorities are considering the possibility that criminals used him as a means to gain access to the cryptocurrency assets held by Hou's family.

The cryptocurrency security environment in April 2026 remains vulnerable. In April alone, losses from hacking exceeded $623 million, an increase from the previous year. This macro context suggests that violent crimes targeting individuals, such as the Naiping Hou case, are not coincidental.

The San Bernardino County Sheriff's Department and the FBI are requesting active tips from the public. Related information may be eligible for compensation review through the California Victim Compensation Board, and authorities plan to mobilize all investigative means for the safe return of the missing person.
