(CNN) -- [Breaking news update, posted at 11:44 a.m. ET]
A grand jury investigating the 2012 rape of a 16-year-old girl in Steubenville, Ohio, has indicted four more people in the case, including the school superintendent, two other educators and an assistant football coach, Ohio Attorney General Mike DeWine said Monday.
This brings to six the number of people the grand jury has indicted after two students were convicted in March of rape, DeWine said.
Superintendent Michael McVey was the only one of the four to be charged Monday with felonies: a count of tampering with evidence and two counts of obstructing justice. He also is charged with two misdemeanors: making a false statement and obstructing official business.
A school teacher and an elementary school principal were charged with failure to report child abuse or neglect. A volunteer assistant Steubenville football coach, Matt Belardine, 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.

Steubenville rape case: 'New developments' to be announced Monday
The Ohio attorney general's office could say Monday whether more charges will be filed in connection with a 2012 rape of a 16-year-old girl that made national headlines.
Ohio Attorney General Mike DeWine will announce "new developments" in a grand jury's investigation into whether other crimes were committed in the case that rocked the small eastern Ohio community of Steubenville, his office said. A news conference is scheduled for 11 a.m. ET Monday in Steubenville.
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.
A grand jury then began probing 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.
Richmond was sentenced to a minimum of one year in a juvenile correctional facility. Mays got two years.
If convicted, Rhinaman could be sentenced to four years in prison, which is longer than the two teens convicted of rape will serve.
