Missing Person in London

A man from London had been missing for three months with no leads and growing concern from authorities and family. While browsing the Missing People website 'https://www.missingpeople.org.uk', we discovered his case and decided to investigate pro bono. Through extensive OSINT research into his background, career, and online connections, we uncovered that after losing his job, he had likely chosen to leave the city to start a new life on his own terms.

Following digital and physical leads, we traced his possible movements through Dover and eventually to Birmingham. we located a small, rarely used X (Twitter) account linked to him through mutual online connections. Using geolocation data embedded in his posts, we confirmed he was indeed in Birmingham. we promptly reported my findings to the appropriate authorities, who later verified that he was safe. He had chosen to step away to take a break and rebuild his life independently.

Background Check on a Potential Threat

A woman approached our firm with concerns that she was being catfished and possibly stalked online by a former partner. While the individual claimed to be living in Germany, several inconsistencies in their communication suggested they might actually be in Canada—her home country. Unable to confirm this herself, she asked us to verify the authenticity and origin of a photo of a mountain range the individual had sent her.

Using detailed OSINT image analysis, we examined multiple visual indicators within the photo, including foliage types, tree species and distinctive mountain peak structures. After correlating these features with topographical and ecological data, we determined that the landscape matched a location in Canada—not Germany. A reverse image search and metadata analysis confirmed the image had not been sourced from the internet, indicating it was likely taken personally. We informed the client that her suspicions were valid—the photo originated in Canada, not Germany—though we did not disclose the precise location to preserve privacy and ensure ethical compliance. Satisfied with the evidence, she chose to report the findings to local law enforcement due to the potential risks involved.
