Cedar Rapids High School Principal Retires After Teacher at School Involved in Scandal

CEDAR RAPIDS, Iowa -- A sex scandal at a Cedar Rapids high school has resulted in a long-time educator stepping down.

Dr. Ralph Plagman has been the Principal at Cedar Rapids Washington High School for 35 years. He announced his retirement Tuesday after district leaders asked him to step down.

This follows a teacher's admission that she had a relationship with a student at the school.

24-year-old Mary Beth Haglin is charged with sexual exploitation over her alleged involvement with a 17-year-old.

The school launched an internal investigation in February, based on rumors of the relationship. Nothing came of it until May, when more information surfaced and the school dismissed Haglin.

However, a miscommunication allowed her to be rehired as a substitute and placed at an elementary school.

She is now in the Linn County Jail.  Haglin told police she's still seeing the boy.
