Inmates at Geiger Corrections Center helped clean up thousands of dollars worth of damage to the city park in Rockford recently.
Three young teens have been charged as juveniles with the vandalism, which was reported May 21. Another boy is facing a trespassing charge.
The vandals damaged the Lyon's Club picnic shelter, fair building and "nearly every other structure and fixture within the park," according to the Spokane County Sheriff's Office.
Seven inmates from Geiger spent about 6 1/2 hours cleaning the park last Thursday.
"The Geiger Inmate Work Crew Program performs manual and skilled labor such as clean up, litter pick up, graffiti removal, forestry work, limited maintenance and other projects for non-profit and government agencies related to public health, safety and welfare," according to a news release.
