He was sentenced to life without parole for the murder.The FBI says Sullivan shot and robbed Clark to get money to help him buy an assault rifle he planned to use to commit the mass murder. He used a rifle he stole from his dad's gun cabinet, which he hid in the crawl space. Sullivan was already serving a life sentence for terrorism, he was sentenced in Burke County last month.Sullivan pleaded guilty last year. He was arrested on June 19, 2015, and charged with attempting to provide material support to ISIL, transporting and receiving a silencer in interstate commerce with intent to commit a felony and receipt and possession of an unregistered silencer, identified by serial number."Those who committed terrorism are not martyrs, they are criminals," the judge said in Tuesday's sentence hearing in Asheville. Sullivan, who called himself The Mujahid in his contacts with the Islamic State, is accused of plotting a mass killing in support of ISIL. “As alleged in the complaint, the defendant was planning assassinations and violent attacks in the United States and is charged with attempting to provide material support to ISIL and federal firearms violations,” said Assistant Attorney General Carlin. “The National Security Division’s highest priority is counter-terrorism and we will continue to pursue justice against those who seek to provide material support to designated foreign terrorist organizations.”According to a criminal complaint, the FBI became aware of Sullivan's plans to obtain a semi-automatic AR-15 rifle at the Hickory Gun Show in Hickory on June 20, 2015, "which he planned to use to kill a large number of U.S. citizens on behalf of ISIL," court documents state. An undercover FBI agent then made contact with Sullivan. “My highest priority is to detect and prosecute violent extremists and protect innocent Americans from terrorist attacks," said Acting U.S. Attorney Rose.Sullivan admitted that he attempted to commit terrorist attacks against innocent people in North Carolina and Virginia, court documents state. Last month, Assistant US Attorney Mike Savage called the killing of John Bailey Clark just a few doors down from Sullivan's home a "Cold blooded killing."
