Search for Lost Hiker in Windy Hill Open Space Preserve
Updated May 19, 2025 at 11 a.m.
After extensive efforts May 2-6 and 16-18, 2025 searching Windy Hill Open Space Preserve and surrounding areas, the coordinated search and rescue operation for the missing hiker, 79-year-old Margaret “Elaine” McKinley, moved into a Limited Continuous Search phase, in accordance with search and rescue best practices. This phase refers to a search operation that continues indefinitely or until the missing person is located, but with resources that are scaled down compared to the initial, more intense phase.
Our thoughts remain with Ms. McKinley’s family and her loved ones during this incredibly difficult time. We urge anyone with information or sightings of Ms. McKinley to call 911.
We also extend our deepest gratitude to Midpen rangers who are working so tirelessly in the ongoing search, and we sincerely thank the San Mateo County Sheriff’s Office as well as all the volunteers, partner agencies and community members involved in this effort.
Further updates from Midpen will be provided on this web page.
