On March 29, 2016, The Pingry School sent a letter to "parents of current students, the entire alumni and school trustees" informing them that the School had "recently learned from a few of our alumni that students were sexually abused by Thad Alton, an employee of Short Hills Country Day School from 1972 to 1974 and, following the merger of the two institutions, an employee of The Pingry School from 1974 to 1978." The letter stated that Pingry had hired a security firm to conduct an investigation on behalf of the school. The letter was signed by Headmaster Nathaniel E. Conard and Jeffrey N. Edwards, chair of the board of trustees.
