Authorities in California and the United Kingdom are searching for a 21-year-old British citizen who vanished during a solo sightseeing trip to Northern California. Katherine Esther Gamboa Kerwood arrived at San Francisco International Airport (SFO) on March 31 for a week-long itinerary, but her family reports she has since gone missing after a series of concerning communication gaps.
The disappearance has sparked an international effort involving the San Francisco Police Department and UK authorities. The case took a troubling turn when the family discovered that Kerwood had never checked into her planned accommodations, despite claiming to be there in her final communications.
According to reports, Kerwood had planned a comprehensive tour of the region, with an itinerary that included visits to San Francisco, Sacramento, Santa Cruz, and Calaveras Big Trees State Park. Whereas she initially contacted her family upon landing at SFO to announce her arrival and her intention to check into a Sacramento hostel that day, she never officially registered at the facility according to KTVU.
Timeline of Disappearance and Communication Gaps
The alarm was raised by Kerwood’s family after a sudden shift in her communication patterns. Family friend Ali Zaidi noted that Kerwood is typically very responsive, making her silence a significant red flag. The last contact the family received was a text message on Friday, in which Kerwood claimed she was still staying at the hostel in Sacramento.
Immediately following this text, the family attempted to speak with her via phone. However, Kerwood did not respond to the request, marking the last time she was heard from. Zaidi told KTVU, “She’s generally very responsive and the fact that she didn’t message for hours is the first signal. Second, when she messaged they said, ‘Hey, let’s get on the phone,’ and immediately she didn’t respond” as reported by SFist.
The discrepancy between her text message and the hostel’s records—confirming she never checked in—has intensified the urgency of the search.
SFO Security Footage and the Identity of “David”
A critical lead in the investigation emerged from security camera footage at San Francisco International Airport. The footage shows Kerwood meeting a man upon her arrival at the terminal. The man was observed carrying flowers for her.
Through subsequent inquiries, the family identified the man as “David,” an individual Kerwood had previously met while in the United Kingdom. The nature of their relationship and David’s current whereabouts are central to the ongoing investigation by law enforcement.
Coordinated Law Enforcement Response
Because the disappearance involves a foreign national and spans multiple jurisdictions, the investigation is being handled by a coalition of agencies. The San Francisco Police Department is leading the local effort, while authorities in the United Kingdom are coordinating with them to gather more information from the UK side.
To broaden the search, authorities across California have been alerted via a statewide law enforcement database, ensuring that officers across the state are aware of Kerwood’s description and the circumstances of her disappearance according to SFist.
