OKLAHOMA CITY - Karen Marinelli, a third-grade teacher at Plaza Towers Elementary School who used her body to shield her students, has finally left the hospital.

Marinelli was badly injured when the May 20 tornado roared through Moore and leveled the school. She laid on top of three little boys and when the walls tumbled down, debris crashed onto her, breaking several bones in her back.

Marinelli was released Friday from Jim Thorpe Rehabilitation Hospital, nearly three weeks after the tornado. She was the only Moore teacher still hospitalized after the storm. She will have to use a wheelchair as she continues to recover and heal.
