It's been nearly a week since a Quad City woman went missing.
Friday, people gathered at Black Hawk State Historic Site to search for any clues.
Now people are going door to door, to spread the word.
No one has seen or heard from Carrie Olson since last Saturday.
Friday night, worried friends passed out flyers around Olson's Davenport neighborhood.
While crime scene investigators were inside Carrie Olson's home Friday night, outside, friends canvassed the neighborhood knocking on doors.
"She's been missing, have you seen her?" asked Loria Woolverton who said she's known Olson since she was a little girl from working at her father's flooring business for 20 years.
"I needed to do something. I couldn't just sit idle. She's like a sister to me. I hope we find her."
Woolverton said it's not like Olson to just disappear.
"She would never go without her cell phone or her wallet. It's not like her to not contact somebody."
Meanwhile family said police interviewed Tim McVay for several hours Friday morning, the last known person to have seen Olson.
The family told CBS 4, he returned Olson's Toyota Avalon Thursday night.
This is what Carrie Olson's father told CBS 4 in an interview Thursday.
"I know he knows something. He wouldn't have her car and charge on her debit card if he didn't know anything," said Dave Olson.
Police have not confirmed those allegations or said if McVay is even a suspect.
We tried to reach McVay on his phone, but it went to voicemail.
His family did not want to comment.
Woolverton said until she knows Carrie Olson is safe, she'll continue passing out flyers.
"This is just a scary situation. I feel that the more people out there getting the word out, that we will find her."
A community Facebook page called 'Find Carrie Olson' has more than 13,000 followers as of Friday night.
There is another search party scheduled for 10am Saturday at Eastern Park in Davenport, near the bike path.
If you have any information that could be helpful to police you're asked to contact them right away.
The search continues for a Quad City woman missing since last Saturday.
Friday people gathered at Black Hawk State Historic Site to search for 29–year–old Carrie Olson. Family members confirm police interviewed the man who was the last known person to have seen Olson for several hours Friday morning.
Olson's family says that man returned in Olsons' car Toyota Avalon Thursday night, but without Carrie. Volunteers searching Friday say they just want answers.
"We just want to help bring this girl home. She's loved, she's an important person to a lot of people. We just want to help find her. Whatever we can do." said family friend Kelli Meyer.
If you have any information on what happened to Carrie Olson, or where she might be, you are asked to call police immediately.
