Redwood City resident McKinley was last seen in the preserve on Thursday around noon hiking the Lost Trail when she became separated from her family. She has dementia and was wearing a red jacket and black pants at the time she was reported missing.
"Unfortunately, since that time, there have been no confirmed sightings of Elaine," the Sheriff's Office said.
Since McKinley was reported missing, hundreds of specially trained search and rescue personnel searched for her.
"Over the last 72 hours, approximately 3,000 total miles have been tracked by searches on ground, either by car or on foot," the Sheriff's Office said.
On Sunday, drone teams arrived from Alameda, Marin and Santa Clara counties to assist San Mateo County's drone team in expanded aerial searches. Drivers and cyclists are asked to keep an eye out for personnel who are searching along state Highway 35.
"The San Mateo County Sheriff's Office continues to ask all residents who live near the preserve to check their cameras day and night, starting on Thursday 10 a.m. and to report this information though an online form," said the Sheriff's Office. "Any sightings, or lack of sightings, on camera footage will help aid in the search."
