Terry Don Knowlton, a 48-year-old man, was last reported seen in San Bernardino, California on December 28, 2020. Publicly available case summaries indicate that he has not been heard from again, and that only limited information about the circumstances has been released to the public.
In the materials that are available, Knowlton is described as a White male with brown hair and blue eyes, approximately 6'2" and about 180 pounds. The publicly shared profile does not provide a detailed timeline of his last-known movements, who he was with, what he was doing that day, what he was wearing, whether he had a vehicle, or what specific leads investigators were pursuing—an absence of detail that can make it especially hard for community members to recognize connections that might otherwise help.
The investigating agency listed in the available case information is the San Bernardino Police Department. The same public summary emphasizes that “few details are available,” underscoring that much of what may be known to investigators has not been broadly published.
A separate public report from June 2025 describes an At Risk/Missing Person alert issued for a man identified as Terry Knowlton who was reported missing in Banning, California. That report states he was believed to be on foot and was last seen in the area of Alutra Place and West George Street; it also provides a description and says he was last seen wearing a gray T-shirt and blue jeans, with the public urged to contact the Banning Police Department. Because that report does not identify him as “Terry Don Knowlton,” it cannot be treated as a confirmed update to the San Bernardino case based on the public record alone, but the similarities make it information worth noting when reviewing what has appeared online about the name.
The California Department of Justice missing-person entry that is cited as a source for Knowlton’s public listing currently displays a “record was not found” message, which can happen for a variety of reasons and it does not, by itself, confirm a resolution or provide clarity about what happened. In situations like this—where families and the public have very little verified detail—accurate tips routed directly to the investigating agency remain crucial, and compassion matters: every day without answers can be its own kind of heartbreak for the people who care about him.
