Yin Cheng, of Sausalito, had last been seen in the 400 block of North Street at 7 a.m. She was getting ready to take her usual one- to two-hour morning walk, police said.
Due to her age, police and family members were concerned for her safety, especially because she had no history of returning home late. She does not speak English, wasn't carrying identification, and didn't have access to money, police said.
She was found shortly before 8 a.m. today in the area of Kirby Cove campground in the Marin Headlands. She appeared to be OK, but was taken to a hospital to be evaluated.
Dozens of searchers, including Sausalito police and Southern Marin Fire Department, had scoured the Sausalito area until midnight and were in the process of expanding the search when she was found this morning.
