More than 200 people are searching a heavily wooded state park in Northern California for a 9-year Santa Fe, New Mexico, girl who was reported missing from her family's campsite.

Marin County Sheriff's Department Lt. Douglas Pittman tells television station KGO that search teams worked through the night looking for Ida Rothschild, who was visiting Samuel P. Taylor State Park with her parents and two younger boys on Friday afternoon when she disappeared.

Pittman says Ida's father last saw her around noon, realized she was gone about half an hour later, and then spent 90 minutes searching for her before contacting authorities.

He says searchers are combing the park's dense redwood terrain. He says at this point investigators do not know if Ida wandered away and got lost or was kidnapped.
