Missing Family Baffles Police

(CBS)  Police in Oregon are baffled by the disappearance of an entire family. Peter Stivers, his wife Marlo, their two children and his parents have been missing for 12 days. The family left Ashland, Ore., on March 4, headed for the coast in a motor home, and hasn't been heard from since.

Rose Hill is Marlo's mother and Lori Mock is her sister. Both women joined The Early Show Thursday to talk about this troubling case.

The family had intended to be gone for just one day, and Hill told co-anchor Rene Syler that her daughter had been very excited about the trip. "She's never seen the ocean before," she said. "We all were raised and born in Arizona. And she was just so excited to be able to go see the ocean."

Hill reported the family missing on March 8, three days after they had been expected home and says that so far, the police are stumped. "They know nothing," she told Syler. "We all think it's just bizarre. It's just like they vanished. We have no information since their disappearance."

One important piece of information is that there has been no activity in the family's bank accounts, which leads police to think this is not a case of foul play. "They are concentrating on a search and rescue at this point," said Mock.

"At this point, I am afraid that they are stranded or snowed in," she said. "So we're afraid they are out there cold and hungry."

The family was traveling in a 35-foot mobile home. Police ask anyone with information about the case to call the Ashland Police Department at [phone].
