Topeka ? The National Park Service says it will replace a plaque at a former Topeka elementary school after a community activist discovered it was missing.

Sonny Scroggins says he went to the school last week and found the plaque designating the former Sumner Elementary School as a National Historic Landmark was gone.

The school was added to the National Register of Historic Places in 1987 because of its role in the Brown v. Board of Education desegregation case in 1954.

The Topeka Capital-Journal reports the school was closed in 1996 as part of a desegregation plan, and sold in January 2009 for $89,000.
