A Maryland man charged with extorting an Indiana teen and others into sexual favors was sentenced in federal court Friday to 33 years and was ordered to pay $5,000.Trevor Shea, 20, of Mechanicsburg, Md., had agreed to plead guilty to seven counts of sexual exploiting children.Shea coerced girls in Florida, Kansas and Maryland into various acts after his release on bond following an initial indictment in June 2010. He had agreed not to use a computer as a term of release.The case was filed in Indiana, stemming from Shea's contact with a 16-year-old girl from Brownsburg.Three teenage girls with a webcam visited an Internet chat room during a 2009 party and yielded to requests from Shea to flash their breasts.A week later, one of the girls started getting threatening emails in which Shea told the girl he had captured her image on the webcam and would post the pictures to her MySpace friends unless she posed for more explicit pictures and videos for him.On at least two occasions, the teen did what her blackmailer demanded, U.S. Attorney Joe Hogsett said.Officials said that one of the girls in a case involving Shea tried to kill herself on camera because of threats from Shea, RTV6's Derrik Thomas reported."They begged for mercy. They pleaded for him to release them from the extortion that he was imposing on them, but he continued to video them for his own sadistic pleasure. That (behavior) will not be tolerated by the U.S. Attorney office in Indiana. Hopefully, we'll never see Mr. Shea again, Hogsett said.Before Shea was sentenced, he showed signs of remorse.No one deserves what I did. What I did was horrible. I find it disgusting and I apologized to my victims, Shea said.Sheas mother said that the 33 year sentence was too harsh."The prosecutor was uneducated. He's not (sadistic), she said.Federal prosecutors called Shea's case an example of "sextortion," or when an Internet predator seeks out and gains access to children and teenagers to sexually exploit and terrorize them.Deputy U.S. Attorney A. Brant Cook said Sheas punishment fit the crime."This was a despicable conduct. It was appropriately addressed by the court (Friday) with a significant sentence that will deter others from this same kind of conduct, Cook said. When Shea is released from prison, he will be on supervised release for the rest of his life. Hell have to register as a sex offender and he cant have contact with children. Hes also not allowed to posses or use a computer.
