BEATRICE, Neb. (AP) — Staff and residents from a Nebraska center for people with developmental disabilities have been visiting a local cemetery around Memorial Day for two decades to ensure former residents are remembered.

A dozen staff members and six residents from Beatrice State Developmental Center visited Evergreen Home Cemetery on Wednesday.

They planted wooden crosses in front of headstones in a section known as Block 47, where more than 200 of the center’s former residents have been buried over the past century.

Dr. Robert Schalock says the facility stopped imprinting patients’ names on their headstones in 1935, and he fears families will forget them.

The center’s active treatment program manager, Tammy Weichel, says decorating graves is a way to make sure nobody is forgotten.
