After pleading no contest, Antrich was sentenced to a 10-year suspended sentence and the rest of the charges were dismissed.
Authorities say Antrich had an on-going sexual relationship with the 17-year-old in October and November of last year.
According to a court affidavit cited by McAlester News-Capital, Quinton Police Chief Tim Reavis was called to Quinton High School November 29, 2012, after getting a tip that a teacher was having an affair with a student.
