Walla Walla police are warning residents about a door-to-door soliciting scam circulating in the area.
The suspects have used different stories as they try to seek donations from residents, said Walla Walla police Officer Tim Bennett.
Stories known so far include asking money to support the "Wounded Warrior Project," or to help the Walla Walla High School softball team to go to Hawaii.
Some scammers also have claimed to be selling magazines to raise money for a school or selling care packages to send to soldiers overseas.
Never miss a local story.
The scammers ask for cash or checks, Bennett said.
At least five victims have been identified, with others possible in Umatilla County and surrounding areas.
One suspect has been described as a girl, 16-18 years old, about 5-foot-6, with blonde straight hair and a slender build.
Residents are urged to call police immediately to report suspicious solicitors and provide suspects and vehicles. Door-to-door solicitors have to be licensed by the city of Walla Walla and must show their credentials, if asked.
Anyone who may have fallen victim to the 'scams should call their banks and stop payment on the checks.
