A week after the disappearance of his wife, Chris Jacobson finds himself fighting to remain optimistic.
He cleans house, walks the dog, plays computer card games and watches baseball to keep "from thinking about what may or may not have happened," he said.
"If you start thinking about all the negative things, you won't get any rest," said Jacobson, his voice trailing off as he held back tears.
Susan Jacobson, 59, was last seen about 6 a.m. May 1 when she told her husband of 35 years she was going grocery shopping and running errands.
Since that time, her car, with her purse inside, was found in an area parking lot. Her wallet minus the cash and credit cards was found and turned in at a nearby Starbucks, authorities said.
Despite the troubling signs, Roseville police investigators are not ready so settle on one theory.
"We are closing the loops on theories," said Sgt. Darin DeFreece.
"Is it a missing person's case? Is it a homicide? Could she have hurt herself? Everything is on the table," DeFreece said.
Jacobson said he sheepishly called the police at around 7 p.m. on the first day of her disappearance.
"I was still unsure sure if I should bother the police with it or not," Jacobson said from the Sun City Roseville home he shared with his wife. "At the same time, it was very unlike her. She is a very regimented, schedule-oriented person."
He also said she didn't have friends with whom she might run off.
DeFreece said police are processing every lead, tip and surveillance video they can get their hands on and they want more.
Any little piece of information from that day could help, DeFreece said.
Some of the evidence being processed came from Sunday's 200-person search party that scoured Mahany Park and open spaces in Sun City Roseville.
He said police are attacking the case with the urgency of a kidnapping and the manpower of a homicide investigation.
"It is so suspicious that we are throwing a lot of resources at it," DeFreece said.
Jacobson is holding onto hope, but he said that with each passing day the likelihood that she isn't just missing or lost increases.
"The longer it goes, it seems that way," said Jacobson, when asked about foul play. "Let me say it's more likely. If she is wandering around, I don't think she would purposely conceal herself."
News about another high- profile missing persons case gave Jacobson reason for optimism.
He said hearing about the rescue of the three Cleveland women after years of captivity made him think: "Maybe there is still hope out there."
"Here after 10 years they were able to get back their families," Jacobson said. But he said he hopes for a faster happy ending.
"Too often you hear about the cases where someone goes missing," Jacobson said, "and what you find one or two weeks later is just a body."
