Michael Knight, 31, of Stonewall pleaded guilty Friday to possession of child pornography, involving a stepdaughter who was 6-years-old at the time.
The Mississippi Attorney General's Office prosecuted the case.
Knight was initially indicted by a Clarke County grand jury in 2009 on seven charges of possession of child pornography and engaging in sexually explicit conduct with a minor.
Knight entered an open plea. The A.G. says that means the defendant refused to accept the state's recommended sentence and threw himself on the mercy of the court.
Knight was sentenced to 30 years in prison, with 18 Years suspended. He will have to serve 5 years probation after his release, must register as a sex offender, and can have no contact with the victim.
Additionally, Knight must pay $1,000 to the crime victim's compensation fund and $1,000 to the Cyber Crime Unit.
"This investigation resulted in our being able to rescue a child," said Attorney General Jim Hood. "Our special thanks to the Department of Human Services for their assistance in this case."
