(CNN) -- A man authorities want to question in the slaying of a 7-year-old girl, whose body was dumped in a landfill, appeared in a Florida court Wednesday on child pornography charges after being extradited from Mississippi. Jarred Harrell, 24, faces 29 counts of possession of child pornography in Clay County, Florida. Clay County Sheriff Rick Beseler has said Harrell is also sought for questioning in the abduction and murder of Somer Thompson, but has not said why. Harrell was arrested in Meridian, Mississippi, by federal agents earlier this month, and Florida Gov. Charlie Crist asked Mississippi Gov. Haley Barbour to extradite him. The arrest followed a search of Harrell's residence, Clay County authorities said.
