David is member of Robert Sheldon and Randy Adderson's gang, which is part of the large, rich west-side group called the "Socs". In the scene where Ponyboy and Johnny run away from home, and a group of Socs jump them at the park, David is the Soc who attempted to drown Ponyboy in the fountain, before running away when Johnny killed Bob (Robert Sheldon).

David does not appear in the film version of The Outsiders.
