Unlicensed Contractor Accused of Scamming $2.9 Million From Older Couple in Half Moon Bay Pleads Not Guilty

The man targeted an older couple with cognitive issues, prosecutors said.

Published on Mar. 2, 2026

A 52-year-old unlicensed contractor named John Wilson has been charged with multiple felonies after allegedly defrauding an older couple in Half Moon Bay, California out of nearly $3 million. Prosecutors say Wilson knocked on the door of the 92-year-old and 82-year-old couple's rural home in 2024 and offered construction services, which the couple agreed to due to their cognitive impairments. The scheme was uncovered in 2025 when the couple's neighbor discovered $2.9 million in payments made to Wilson across 57 checks, far exceeding the value of their home. Wilson has pleaded not guilty and is currently in custody.

Why it matters

This case highlights the vulnerability of older adults with cognitive issues to financial exploitation and fraud, as well as the need for stronger oversight and regulation of the home repair and construction industry to protect consumers, especially those who may be more susceptible to scams.

The details

According to prosecutors, Wilson, an unlicensed contractor, allegedly performed months of extensive and unnecessary repairs on the couple's home, including work on their kitchen, bathroom, basement, and the installation of solar panels. The California State Contractors Board later assessed the value of the work Wilson allegedly performed at just $217,350, a small fraction of the $2.9 million the couple paid him.

  • In 2024, Wilson allegedly knocked on the couple's door and offered construction services.
  • In March 2025, the couple's neighbor discovered the $2.9 million in payments made to Wilson while assisting them with their taxes.
  • On June 15, Wilson is scheduled to return to court for further proceedings.
