HASTINGS, Neb. (AP) — A former Hastings High School teacher accused of having sex with a 15-year-old student has been given a year in jail.

Court records say 39-year-old Johnathan Shafer was sentenced Wednesday in Adams County Court. He’d pleaded no contest and was convicted of contributing to the delinquency of a minor and negligent child abuse. In exchange for Shafer’s pleas, prosecutors dropped a sexual assault charge that carries a maximum sentence of 15 years.

The plea deal was made after the girl told police she had been mistaken on the time frame and that she was 16 when the relationship began in the summer of 2013. Nebraska prohibits people 19 and older from having sexual contact with people younger than 16.
