Bay Area woman defrauded of $5,400 in AI voice-clone kidnapping scam
Scammers allegedly used AI voice-cloning technology to mimic a woman's daughter in a fake kidnapping call, convincing the mother to wire $5,400 to Mexico over five hours. Martinez police are investigating the incident, which authorities describe as part of a growing trend of voice-cloning fraud.
What happened
In May 2026, scammers called Deborah Del Mastro, claiming her 37-year-old daughter had been kidnapped by a Mexican drug cartel. They played audio they claimed was her daughter's voice expressing panic and fear.
Over five hours, the caller issued urgent commands, instructing Del Mastro to withdraw money. She wired $5,400 to Mexico from multiple locations following the caller's instructions. When she went to a grocery store to retrieve her daughter, she discovered the kidnapping was a hoax and called her daughter directly, learning she was at work.
Reported impact
Del Mastro lost $5,400 to the scam and said she does not expect to recover the money.
