LEE COUNTY, Fla.- A Lee County man will serve 30 years in prison after pleading guilty to molesting a child.

Police arrested Alan Johnson after someone found child porn on his cell phone when it was dropped outside of a Walmart. Johnson was already sentenced to 50 years in federal court. He will serve his time concurrently with the federal sentence, and is ordered to have no contact with the victim.

The second suspect in this case, Johnson's girlfriend, Jennifer Sparks, will also spend 30 years behind bars. That will also run at the same time as her federal sentence. After she's released, she will have to register as a sex predator and was ordered to have no contact with the victim.
