LAWRENCE, Kan. (AP) — A former Lawrence school district para-educator has been sentenced to nearly three years in prison for having sex with a student.

Thirty-four-year-old Teri Lynn Johnson, of Baldwin City, was sentenced Friday. She was convicted in March of unlawful sexual relations and sexual exploitation of a child, both felonies, and promoting obscenity to a minor, a misdemeanor. Johnson must also register as a sex offender.

The Lawrence Journal-World reports the crimes occurred in fall 2015 when the victim — then 17 — was a student at the Douglas County Juvenile Detention Center’s Day School. Prosecutors say the conduct lasted until December of that year.
