Summary based on the NamUs case record (MP12598) and 3 other sources
Gregory Charles Dugas, aged 42, was last seen on September 2, 1992, in Inverness Park, California. He was dealing with personal challenges, including the recent end of a 12-year relationship with his girlfriend, which reportedly led to mood swings. However, in the days before his disappearance, his friends noted that his behavior had returned to normal.

On the day he vanished, Gregory had canceled plans to meet with a friend to repair his 1983 Ford Ranger. He took approximately $700 in cash, borrowed from his father for the vehicle repairs, along with his house keys and a small blue backpack, which he regularly carried on errands. His vehicle and most of his belongings were left behind at his home, and he has not been seen or heard from since.

Gregory was known to be an active environmentalist and enjoyed outdoor activities such as hiking, backpacking, and mountain biking. While some speculated that he may have left voluntarily due to his personal struggles, his family and friends considered it highly uncharacteristic for him to abandon his life without warning. His case remains unsolved, and authorities have not determined whether foul play was involved.
