Sheriff’s deputies resumed searching today for a man who never came home from a Thursday evening hike in the rugged Skeggs Point area of unincorporated San Mateo County. Douglas May, 55, left his home in San Carlos around 5:30 p.m. to go hiking, but family members became alarmed and contacted the sheriff’s office when he never returned. A sheriff’s deputy found May’s car just before 1 a.m. Friday in the Skeggs Point parking lot. Authorities do not suspect foul play but believe May could be lost or injured. Sheriff’s office spokeswoman Sgt. Linda Gibbons described the terrain in the Skeggs Point area as “dense and hilly.” It is steep and rugged and there is thick manzanita, which makes searching challenging, authorities said. The San Mateo County Sheriff’s Office and the county’s office of emergency services expanded the search off the main trails in the area. Skeggs Point is part of the Midpeninsula Regional Open Space District, located on state Highway 35, south of state Highway 92. The search resumed at 6 a.m. today and was staffed with 122 search and support personnel. Anyone with information on May’s location should call Detective Marcus Gathright at (650) 363-7823.
