JOHNSON CITY, Tenn. (AP) -- Someone obviously not bothered by heights has painted two large faces high on a silo at a former General Mills plant in Johnson City.

Police say they have no leads on who spray-painted the images on the building over the weekend.

The plant is owned by the Johnson City-Jonesborough-Washington County Chamber of Commerce.

Chamber President and CEO Gary Mabrey told the Johnson City Press he hopes nobody gets hurt while painting graffiti and says the group will prosecute if the culprits are caught.

Early this year, someone scaled the five-story building and spray-painted "We're all gonna die."

Johnson City Police are patrolling the plant more often and ask anyone seeing people painting graffiti on it to call 911.
