A self proclaimed satanist, who on social media used the screen name "The Lord of Darkness," has admitted to molesting three little girls, taking pictures of the assaults and then trading those images online with other child pornography collectors.

Luis Moreno, 31, pled guilty today to 12 counts of production of child pornography, two counts of the receipt of child pornography and two more counts of the possession of kiddie porn.  He faces up to 420 years in federal prison when he's sentenced in November.

The case was a joint investigation by The San Antonio Child Exploitation Task Force involving the FBI and the Bexar County Sheriff's Department.

Assistant US Attorney Tracy Thompson said investigators were originally tipped off to Moreno when they busted another pervert in Indiana.  They asked to assume his profile online.  That's when agents received dozens of emails filled with illicit pictures from Moreno. 

"He has been sexually assaulting these three minor females for six years," she told the judge.

The case was difficult for agents because Moreno is basically a drifter who lived in different homes.  He did not have a computer.  Instead, he created the child pornography using a HTC Mytouch 4g cell phone, a Nintendo DSI video game system and a Hotmail email address.  They eventually caught up to him in a seedy apartment on Grayson Street, not far from the entrance to Ft. Sam Houston.

While he pled guilty to taking pictures of the prepubescent girls private areas, he vehimetly opposed the idea that he had full sexual intercourse, despite prosecutiors claims they had photos to prove the opposite.

"Those images must have been images I received from other people," he pled with the judge, who said he would have time to explain that during sentencing.

Moreno, who had tattoos of a pentagram and the Grim Reaper up and down his body, has a lengthy criminal history, including Aggravated Assault with a Deadly Weapon in in 1999.  He attacked a girlfriend with a samurai sword.

The three victims, who were all attacked when they were three years old, are all in protective custody.
