Nile Baker, 83, was found later Thursday and was returned to Hayes Valley Care, the assisted living home in the 600 block of Laguna Street where he lives, Esparza said.
Baker was seen walking out of the center on Thursday morning. Concern was raised when he did not immediately return because he does not know his address or how to get back to his home due to his dementia, police said.
Information about where Baker was located or his condition was not immediately available.
