ATCHISON COUNTY, Kan. -- There are 13 white ribbons tied to Patricia Kimmi's front fence at her home in Atchison County.

Each ribbon was put there by a grandchild as family continues its search for the missing woman. Family members said on Thursday that they won't stop looking for Kimmi and they don't want others to stop either so they have increased the reward to $10,000 for any tip that leads to an arrest or finding their lost loved one.

Kimmi was reported missing nearly two weeks ago after she failed to meet a friend for a shopping date. The Atchison County Sheriff's Department found what they called obvious signs of foul play at her home.

Hundreds of volunteers searched a total of 900 square miles where they found items that investigators believe are related to Kimmi's disappearance.

The latest search turned up a money clip and a camouflage hat. Authorities are looking for the owner of the items.

Another organized search will begin at 9 a.m. on Saturday at the Horton, Kan., fire house. The group is looking for volunteers to help in the effort.
