Richard Dean Davison, 70, was last seen on October 29, 1997, leaving his Los Angeles residence to go to a doctor’s appointment and never arrived. He is described as 5 feet 10 inches, about 145 pounds, with gray thinning hair, brown eyes and wearing eyeglasses. Authorities believe he may be in a hospital or nursing facility, but he has not been located and the case remains unsolved.

Davison was one of several patients who disappeared either en route to or after visiting the same physician in Los Angeles around that time. Goldie Swanger disappeared in the same year and was later found in 2004, and Robert Black, a patient from 1996, is also associated with these concerns; no definitive connection has been established among the cases.

If anyone has information about where Richard Davison might be now or recalled seeing him around October 29, 1997, please contact the Los Angeles Police Department.
