According to Snopes.com, four out of five bills have traces of cocaine on them

That factoid came to mind while reading the last paragraph of the passage below:

Knutson was working at the Fryn' Pan in Moorhead, Minn., when, according to her attorney, Craig Richie, a woman left a to-go box from another restaurant on the table. Knutson followed the woman to her car to return the box to her.

"No I am good, you keep it," the woman said, according to the lawsuit.

Knutson did not know the woman and has not seen her since, Richie said. Knutson thought it was "strange" that the woman told her to keep it but she took it inside. The box felt too heavy to be leftovers, Ritchie said, so she opened it -- only to find bundles of cash wrapped in rubber bands.

"Even though I desperately needed the money as my husband and I have five children, I feel I did the right thing by calling the Moorhead Police," Knutson said in the lawsuit.

Police seized the money and originally told Knutson that if no one claimed it after 60 days, it was hers. She was later told 90 days, Richie said. When 90 days passed, Knutson was still without the $12,000.

Police told Knutson the money was being held as "drug money" and she would receive a $1,000 reward instead, the lawsuit states. Lt. Tory Jacobson of the Moorhead police said he could not disclose much information about the case because it is an ongoing investigation.

"With turning this money over to us, we initiated an investigation to determine whose money this is," Jacobson told ABC News. "The result has been a narcotics investigation."

Police argue that the money had a strong odor of marijuana and therefore falls under a law that allows for forfeiture of the money because it was in the proximity of a controlled substance, the lawsuit states. But there were no drugs in the box and Richie said he believes this law is not being used correctly.
