A grand jury in the Maine West hazing investigation is using subpoenas to look at the records of several school officials.

According to the Chicago Sun-times, the Cook County Grand Jury sought records from the superintendent of Maine Township School district, as well as the principals of its three high schools.

Several former and current Maine West students say they were victims of hazing and sexual assault while on school athletic teams.

School officials suspended Maine West soccer coach Michael Divincenzo last month, after he was accused of knowing about the hazing.

Divincenzo has appealed that ruling.
