Authorities say they are searching for a family of four who have been missing for more than a week.

The El Dorado County Sheriff's Office says Sarah Jean Smith and her boyfriend Jason James McClellan were last seen Oct. 20 with 7-year-old Joshua Bargus and 1-year-old Kylie Jean Jus.

The sheriff's office says the couple had gone to pick up the boy with the 1-year-old in the car, and they haven't been heard from since.

A relative reported them missing three days later.

They were in a 2004 silver Honda civic. The relative told authorities that the family did not have plans for a trip.

Smith is 28 years old and McClellan is 40. The family is from the Georgetown area, northeast of Sacramento.

Authorities say there are no signs that foul play was involved but the family could be at risk.
