San Rafael Police conducted a thorough search of the area fearing that Williams was endangered due to what her family described as high blood pressure and symptoms of the early stages of dementia, according to police.

The Marin Search and Rescue Team was called to assist due to the steep terrain in the area, and found Williams on a dirt trail at the end of Sterling Way in about half an hour, according to Santa Rosa Police Lt. Dan Fink.
