A former Oklahoma substitute teacher has received a 10-year suspended sentence in the rape of a 17-year-old male student.

Andrea Antrich, 24, pleaded no contest in Pittsburg County District Court last month to a felony charge of second-degree rape for having a sexual relationship with the teen.

Miss Antrich, of Quinton, was originally charged in December with five counts of second-degree rape. She faced up to 15 years for each count.

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.

Confession: When confronted by police last November about allegations of sex with a minor, Antrich admitted that she and the 17-year-old boy had an ongoing relationship that began October 1, 2012

Reavis interviewed the 17-year-old and found out that the boy and Antrich have been meeting at her home after school for sexual encounters since October 1.

When the police chief confronted the 24-year-old teacher about the allegations, Antrich confirmed that she and the student did have a sexual relationship, according to the affidavit.
