“Other than that, she is a perfectly capable female and does regularly walk and regularly attend her local gym,” said San Bernardino County Sheriff’s Department Cpl. Robert Whiteside.

Sworn sheriff’s deputies were Monday working alongside 20 search-and-rescue team members, in unified command with Huntington Beach police, Whiteside said.

All-terrain vehicles were searching for Norman on rough dirt roads, he said.
