Rochester, MN (KROC AM News ) - An employee of a Rochester convenience store became suspicious earlier this week when she went into the women’s restroom and spotted shoeprints on the toilet seat.  

She decided to check the drop ceiling area and found a bag containing packages of methamphetamine that police say has a street value of at least $75,000.

The discovery was made Wednesday afternoon at the Holiday store on 4th St SE.

Police are checking the store’s surveillance system to see if a suspect can be identified.
