Virginia Calonsag lives in Elk Grove but had been visiting her son in Daly City when she left his home at 200 Coronado Ave. between 7:30 and 8:30 a.m. Police said no one saw her leave.
Calonsag did not take her cell phone or wallet with her when she left but was thought to be carrying her aluminum walking cane that has her phone number on it.
Police were especially concerned because on June 20 Calonsag went for a walk from her Elk Grove home and was later found 2 miles away, facedown in a creek. Her family says she had been kidnapped and robbed.
The woman was found in good condition at the Daly City BART station around 10:45 p.m. Thursday and was reunited with her family, police said.
