A Virginia man has been sentenced to 20 years in prison by a Kent County Judge after pleading guilty to 2 counts of dealing in child pornography.  30 year old Sean Smith of Manassas was extradited to Delaware last August after he shared images of child pornography with an undercover detective.  A separate undercover investigation led to a warrant served at a Wilmington home Thursday after Child Predator Task Force members obtained a video of child pornography online.  Detectives arrested 54 year old Thomas Fort and seized multiple computers and digital storage devices.  A Newark man was also arrested on January 11 after a video was received by Task Force members from 22 year old Juan Miguel Mendez-Rosario.
