PRINCE GEORGE, Va. (AP) -- A former Prince George County junior high school teacher has pleaded guilty to using a computer to solicit a former student for sex.

Lloyd Tyrell Alston of Greensboro, N.C., was sentenced to one year in prison after entering his plea Thursday. After release, he will be required to register as a sex offender.

According to the state attorney general's office, the 32-year-old Alston, who later became a preacher in North Carolina, used social networking sites and text messages to engage in sexually explicit conversations with the girl. She showed the messages to her father, who contacted Virginia State Police.
