Texas Grandmother Says She Found Bag of Cocaine Inside Granola Bar Package

Police say they’re working to solve the mystery.

— -- A Texas grandmother eating a granola bar says she was shocked to discover a bag of cocaine at the bottom of the package.

San Antonio resident Cynthia Rodriguez, 60, said she found the substance inside a small plastic bag about the size of a quarter with green dollar marks on it that was tucked into the bar's wrapper.

“I was munching it from the wrapper, and when I finished eating it, I like the crumbs, so I shook it out to get them and the little packet popped out in my hand,” Rodriguez told ABC News today.

At first, Rodriguez said, she thought it was a promotion and she had won a prize. So she called the maker of the Nature Valley granola bar, she said, but officials there told her to call the police.

“[The police] tested it and said, ‘Congratulations, this is high-quality cocaine,’” Rodriguez said.

San Antonio police started investigating in March, when the incident first happened.

“The narcotics unit is following up on it,” Sgt. Javier Salazar told ABC News today. “[The bag] had a fairly decent amount of cocaine. ... To a child, it could seem there was candy or something more innocuous in there.”

That’s what Rodriguez was afraid of -- the fact that one of her 11 grandchildren could have opened the wrapper.

“What if one of my grandkids had eaten it?” Rodriguez said. “I still have other boxes of Nature Valley and we haven’t touched them because I’m so afraid.”

Police say they’re working to solve the mystery, and no legal action currently is being taken. The narcotics team is trying to find where the granola bar was packaged, which could help them find a suspect.

Rodriguez said she did not purchase the box of granola bars at a store, but got it for free from a family friend. Salazar did not know whether or not detectives on the case had yet spoken to that family friend.

Possession of cocaine or delivery by any means is a felony, Sgt. Salazar said. The perpetrator could face additional charges if possession or tampering with a product is discovered.

“Something like this happening is rare, but one time is too many,” Salazar said.

General Mills, which owns the Nature Valley brand, said in a prepared statement, "We are confident this did not happen in our facility and referred this to the police department back in March."

The company would not answer additional questions, but company spokesman Mike Siemienas told ABC News affiliate KSAT, "Inside the production facility, the product moves very fast and it would be extremely difficult to get something in there."

Rodriguez said she doesn’t plan to file a lawsuit but wants to know what happened.

“I’m still waiting for Nature Valley to get back to me to see if they found the culprit ... but they’ve never called me back,” Rodriguez said.
