A former Delaware middle school English teacher must register as a sex offender after she admitted to raping a 13-year-old boy.

Former Fifer Middle School teacher Stephanie Seabury pleaded guilty to one count of fourth-degree rape in Kent County Court Wednesday, said the Delaware Department of Justice.

A judge sentenced Seabury to 18 month probation. She must also register as a Tier II sex offender and have no contact with either the victim or other children.

Seabury was 22 when she surrendered to Dover Police in late April on sexual abuse charges.

Police said the first-year teacher would meet her teenage student and then drive him to her unit at Woodmill Apartments on S Farmview Drive in Dover.

"It was a very highly inappropriate relationship," said Dover Police Cpl. Mark Hoffman. "Especially with a 13-year-old and a 22-year-old, and, of course, being a teacher."

Police said that on Feb. 26, Seabury and her student were captured on surveillance video leaving the Caesar Rodney School District school and getting into Seabury’s car. Investigators said Seabury then drove the teen to her apartment where the two had sex.

Police learned of the alleged assault on March 12 and began to investigate. That investigation revealed a series of “explicit phone message and photographs during the inappropriate relationship,” police said.

Seabury was booked and released April 28 after her parents helped her post $40,000 secured bond. The Long Island, N.Y. native and University of Delaware graduate had no comment as NBC10 cameras exclusively captured her leaving custody and driving off in a sport utility vehicle the day of her surrender.

Seabury was suspended then dismissed from her job.
