Summary based on the NamUs case record (MP12453) and 3 other sources
Gregory Grant Orr, a 42-year-old man from San Rafael, California, was last seen on February 24, 1993. On the day of his disappearance, Gregory was supposed to pick up his son from middle school, a routine task that he did not complete, which was highly uncharacteristic of him. He was last seen at his home by his mother before he vanished, and no one has heard from him since.

Gregory had a known medical condition at the time—he was HIV-positive and taking medications that could be harmful, although it appears he was unaware of the risks associated with his medication. He also had a history of drug use, which might have contributed to his vulnerability. His disappearance remains a mystery, as no significant leads or evidence have emerged over the years. Gregory is described as a white male, standing 5'11" tall and weighing 135 pounds. He had brown hair, green eyes, and several tattoos, including a Viking head and a pirate on his arms.

Despite the efforts of investigators and his family, no clues have surfaced regarding his whereabouts, and the case remains open. Gregory's sudden disappearance without any trace has left his loved ones searching for answers for over two decades.
