Dec. 3 at 3:16 pm A man who worked as an investigator for conspiracy theorist Jack Burkman will serve a nine-year prison sentence for firing and wounding his former boss in a complicated plot involving a false FBI briefing. Kevin Doherty, 46, said little about the fact that Judge William T. Newman Jr. sentenced him on Monday for inflicting malicious wounds and using a firearm to commit a crime. his "serious argument" with Burkman and the "great ruse" he concocted for revenge. Eastman said Doherty had attracted Burkman to a covered parking garage in March with the false promise to reveal details of the FBI's misconduct. "It was pretending," said Eastman. During the hearing held at the Arlington Circuit Court, Newman imposed a sentence of 23 years of imprisonment at 14 years suspended. In addition, Doherty, who pleaded guilty to both counts, must repay with interest Burkman's $ 15,000 for non-existent FBI documents. Burkman told the Washington Post in March that he had hired Doherty, a former sailor, to investigate the death of Seth Rich, a member of the Democratic National Committee. Burkman, a Republican lobbyist, is rooted in a conspiracy theory that Rich was reportedly killed for sending Democratic e-mails to WikiLeaks. Law enforcement described the homicide as robbery on the street and Rich's family repeatedly sued the right-wing media for falsely stating the opposite. Doherty was supposed to establish a psychological profile of Rich's possible killer, but Burkman said in March that he and Doherty had quickly disagreed over control of the project. Burkman dismissed Doherty in July 2017. In court, Eastman described the plot Doherty had executed months later and described how the police found him. Doherty has sent emails to Burkman claiming to have information "damaging to the FBI". Burkman paid $ 15,000 to Doherty and arranged to retrieve the documentation under a traffic cone at the Key Bridge Marriott in Arlington on March 13th. When Burkman was bent over to get the documents. Eastman said, Doherty shot him twice in the buttocks with a rifle. Burkman escaped by a parking ramp, carrying the traffic cone and his dog. Jack Jr. Doherty admitted that he had then overthrown his former employer since driving a black SUV. Burkman had a broken arm and two bullets remain lodged in his buttocks, said Eastman. His dachshund was not injured. Doherty started before the police arrived, but Eastman said the black sport utility vehicle had been sighted in the garage by hotel security cameras before the attack. A man was seen leaving the vehicle and putting several items in a trash bin nearby. Inside the tin can, police found a shipping box addressed to Doherty and a handwritten note on the calibration of a new weapon, as well as fuel filters and ammunition . Police quickly learned that Doherty had rented a large black SUV from Hertz at Reagan National Airport that morning. Hertz's GPS location showed that the vehicle had been driven to the Marriott Hotel, then took a "back-road" to Boston after the attack, Eastman said. She added that Doherty had returned the utility vehicle to Boston and bought a new rental car. The $ 15,000 Burkman paid was found in Doherty's bank account, the attorney said. Doherty was arrested in Arlington on March 17. On his computer, Eastman said the authorities had found emails intended for Burkman, as well as research on the use of a fuel filter as a silencer. At home, they found the rifle used during the attack. She said that the weapon had been sent there. The agreement between Doherty and the prosecutors included the recommended sentence and their agreement to drop a second malicious charge. The judge also ordered that after he was released from Doherty prison, he be held away from Burkman and his family. Burkman did not appear in court and could not be immediately contacted for comment. In March, when the lobbyist spoke with The Post, Burkman said his interest in Rich's theory of death and conspiracy remained generally strong. Last month, Burkman held a press conference during which he claimed to have talked to a woman victim of inappropriate behavior by special advocate Robert S. Mueller III. No such woman has appeared. .
