(CNN) -- A grand jury investigating the 2012 rape of a 16-year-old girl in Steubenville, Ohio, has indicted four school employees, including the school superintendent, who faces felony charges, Ohio Attorney General Mike DeWine announced Monday.
Steubenville City Schools Superintendent Michael McVey faces three felony counts: one charge of tampering with evidence and two counts of obstructing justice. He also is charged with making a false statement and obstructing official business, both misdemeanors, DeWine said.
Also indicted was elementary school principal Lynnett Gorman and wrestling coach Seth Fluharty, both of whom are charged with misdemeanor failure to report child abuse. Volunteer assistant Steubenville football coach Matt Bellardine was charged with four misdemeanors: allowing underage drinking, obstructing official business, making a false statement and contributing to the unruliness or delinquency of a child.
This brings to six the number of people the grand jury has indicted after two students were convicted of rape, DeWine said. A school technology director and his daughter were indicted in October.
In March, Steubenville High School football players Ma'lik Richmond and Trenton Mays were convicted of the rape, which authorities said took place at a party in August 2012. Photos and videos of the incident made their way onto social media and attracted national attention, rocking the small eastern Ohio community.
Richmond was sentenced to a minimum of one year in a juvenile correctional facility. Mays got two years.
A grand jury then began investigating whether others should be charged. In October, it indicted William Rhinaman, 53, the director of technology for Steubenville City Schools, on charges of tampering with evidence, obstruction of justice, obstructing official business and perjury.
His daughter, Hannah Rhinaman, 20, of Mingo Junction, Ohio, was also indicted that month on two counts of receiving stolen property and one count of grand theft, according to a news release from DeWine's office.
The charges against Hannah Rhinaman are separate and unrelated to the indictment against her father, the October news release said.
If convicted, Walter Rhinaman could be sentenced to four years in prison, which is longer than the two teens convicted of rape will serve.
