A former Seminole County high school teacher who pleaded guilty last September to enticement of a minor and production and receipt of child pornography was sentenced to prison Thursday.

Gregory A. Vaughn, 59, was sentenced to 27 years in federal prison and must serve a life term of supervision following his release and register as a sex offender.   He was also ordered to pay $7,500 in restitution.

Vaughn was arrested in June after investigators say he exchanged sexually explicit pictures with a teenage girl.

The mother of the victim, who lives in Colorado, called Seminole County authorities in May when she said she discovered her daughter's ongoing exchanges with the former Hagerty High School teacher.

According to court documents, Vaughn began trading explicit photos with the teenage girl in December in exchange for money, books, candy, clothes, women's underwear and even special-effects makeup.

Investigators said they were able to recover images of the victim and other children from Vaughn's computer.

FBI agents also interviewed another victim, who had also been groomed and enticed into producing child pornography by Vaughn.
