A Canadian named Karl Van Roon was found living as a homeless person in Brazil, having disappeared for four years, and died from a pulmonary embolism before his identity was confirmed.
Karl Van Roon, a Canadian who disappeared from Vancouver in 2022, was discovered living on the streets in Santos, São Paulo, Brazil, after his family used artificial intelligence to trace him. For years, his parents, Heidi and Terry Van Roon, sought information about their son, but it was only in 2025 that they utilized an AI tool to analyze a photo of him. This led them to a news article published in June 2024 by A Tribuna, which described a homeless man communicating in sign language and understanding English and Italian, thus linking him to Karl.
Sadly, Van Roon had already passed away due to a pulmonary embolism and was buried as an indigent in Brazil before his family could reunite with him. The story highlights the struggles faced by individuals living on the streets and sheds light on the tragic circumstances surrounding homelessness. It also demonstrates the potential of technology, such as AI, to reunite families with missing loved ones, albeit too late in this case.
This incident not only raises awareness of the homelessness crisis in Brazil, particularly in urban areas like Santos, but also brings to the forefront the challenges faced by families of missing persons. The emotional toll of such disappearances is exacerbated by the lack of resources available to search for loved ones, underscoring the need for more support and effective tools for families in similar situations.
