Authorities are looking for a former California Highway Patrol officer suspected of molesting his children and possessing child pornography.

Police say 35-year-old Ken Fox of Oakland abused two of his four children, who range in age from 1 to 8. His wife, 26-year-old Brandie Fox, the children's stepmother, is also accused of abusing the two kids.

She was arrested Wednesday in San Diego on suspicion of lewd and lascivious conduct and possession of child pornography.

Police say the kids, who lived with their biological mother, were encouraged to fondle their stepmother and talk about bondage during visits to the couple's home.

The California Highway Patrol says Ken Fox resigned in 2008 after four years with the agency.
