State troopers executing search warrants last week seized three large caches of child pornography in Louisiana, including videos depicting the rape of infants, in a series of raids that led to three arrests.

Overall, according to State Police, its Special Victims Unit found more than 1 million illicit files scattered across 800 DVDs, 13 portable storage devices, cellphones and laptop computers.

It was the largest seizure of child pornography in Louisiana Department of Public Safety and Corrections history, authorities said.

Steven Paul Lucia, 30, was arrested in LaPlace on Friday after detectives searched his house. Lucia was arrested on counts of distribution of child pornography and possession of marijuana.

On the same day in Shreveport, State Police detectives arrested James Dalton Vail, 51, who police said was found to be in possession of more than a million child pornography files. He was booked on 51 counts of distribution of pornography involving juveniles and 1,500 counts of possession of child pornography.

On June 8 in Avoyelles Parish, local and state authorities raided the Hessmer house of Nicholas Bordelon, 35. He was booked on more than 300 counts of possession and distribution of child pornography, State Police said.

Police said their investigation is continuing. They asked anyone with tips about the three men arrested to call detectives at (318) 484-2194.

“We created the Special Victims Unit for exactly this purpose with a focus on rescuing victims and targeting perpetrators of crimes involving the exploitation of children and the trafficking of humans for sex or labor,” Col. Mike Edmonson, the State Police superintendent, said in a statement.

“The Louisiana State Police will employ all available investigative resources and will remain vigilant as long as individuals choose to possess, distribute and promote child pornography.”
