12 year old Wauketta Wallace was labeled as a troubled youth. His death was result of a failed restraint.
There was a probe into this tragedy but his death was ruled as accidential.
It would take additional deaths before a pattern emerged showing that face-down restraints were deadly. Hopefully it was a lesson learned for the staff at Maryville Academy which continues to be in operation today.
