Summary based on the NamUs case record (MP1275) and 6 other sources
Jeffrey Leland Lowery, 23 years old, was last seen on November 12, 1981, in San Luis Obispo, California. Jeffrey had been suffering from severe depression, and on the day of his disappearance, his mother drove him to a mental health facility for treatment. Upon arriving at the facility, Jeffrey abruptly fled the car and was never seen again. At the time, he was wearing a light jacket, dark-colored t-shirt, blue jeans, and was without shoes or socks.

Despite his disappearance occurring in 1981, Jeffrey wasn't reported missing until nearly two years later, in September 1983. This significant delay in reporting has added to the challenges investigators have faced in resolving his case. His case remains unsolved, and few details have emerged over the years to provide clarity on what happened to him after he fled the facility.

If you have any information regarding Jeffrey's case, you are encouraged to contact the San Luis Obispo County Sheriff's Department, which is actively seeking tips that could help bring closure to his family after decades of uncertainty.
