CORVALLIS, Ore. - A man entered a 7-Eleven in Corvallis around 4:30 a.m. Wednesday and bought a Dr. Pepper, a donut, lottery tickets and a pack of cigarettes.
The man handed the clerk two $20 bills and left.
Later that morning, the same man went into another 7-Eleven.
When he handed the clerk a $20, the clerk noticed something strange about the bill. He confronted the man about the bills - and the man dropped the merchandise and ran off.
When General Manager Raj Singh came into work a few hours later, he found two fake $20 bills. He checked video surveillance footage - and called Corvallis Police.
SECURITY FEATURES: How to spot a legit $20
Police located Danny Caldwell and arrested him on counts of forgery and theft.
That same day, a man said to be a regular at Elmers Pancake House just a mile down the road from 7-Eleven had a meal. He paid his waitress with two $10s and a $20.
Immediately, the server said she felt the bills looked too small and didn't feel normal.
Elmers employees contacted police, and Craig Smith of Corvallis was arrested for forgery and Possession of Meth.
Police said they're still investigating whether the two incidents are related.
Corvallis Police Captain Dave Henslee said this isn't the first time they've seen counterfeit bills.
In past cases, he said "people were printing them themselves, other times they've come into town from outside sources, outside of Corvallis."
So how do you spot a counterfeit bill?
Officer Henslee says "when bills are photocopied, you won't feel any raised pictures or any raised markings"
Singh uses a special pen to check a bills legitimacy; one that writes black on paper and turns maroon on bills. He says you can also hold a bill up to the light to identify it's watermark
Police said "if you don't see the presence of a security strip, it's likely counterfeit."
They also ask if you think you've been handed a counterfeit bill, to call local law enforcement.
Hold onto the bill for police to use as evidence in order for them to track down its source and put a stop to it.
