The wife of an Illinois high school football coach -- who worked as a teacher at the school -- has been placed on administrative leave after being charged with computer tampering for allegedly inflating the grades of students, the majority of them being athletes.

Sara Glashagel, 27, of Elk Village, Ill., was charged with hacking into the Antioch High School computers on five separate occasions over a week-long period in September, school district co-superintendent Michael Nekritz said Tuesday.

The special education teacher, who is married to Antioch head football coach Brian Glashagel, is accused of changing the grades of 64 students, with 41 of those being football players, WMAQ-TV reported.

Authorities said she admitted to targeting students who were on the athletic ineligibility list.

The affected students' grades have all been corrected, the school said, adding that Glashagel had been tampering with the grades remotely.

Antioch police Chief Craig Somerville told The Chicago Tribune that Glashagel admitted changing the grades but did not offer a reason. She also said her husband had nothing to do with it.

Glashagel is scheduled to appear in Lake County Court on Dec. 9, the Chicago Sun-Times reported.
