Shawn Christy, the McAdoo man on the run from law enforcement for three months, may have injured his knee during his flight. Karen Christy, his mother, said she and her husband, Craig, learned of Shawn’s injury from a Facebook post he made Thursday night. “I think I shattered my knee during a MD (Maryland) getaway, so I’ve been slowed down a bit,” he said in the message, which was posted around 11 p.m. “Stay safe, I have a mission to complete.” Federal marshals believe he was on his way back to Pennsylvania from Kentucky on Aug. 19 when he was seen sleeping in a vehicle in Cumberland, Maryland, but woke up in time to run from police. The injury may have occurred then. On Facebook, Craig posted a photo of his son, with printing over the photo that says, “Believe in something. Even if it means sacrificing everything.” Karen Christy said she and her husband were not looking at Facebook when their son posted the message Thursday night. “By the time we saw it (the message), he was already off” Facebook, Karen said. “We missed him by 22 minutes.” In August, Christy’s parents left this message for him on Facebook: “Praying your safe tonight Shawn Christy and that you will give up and come home. We sure do miss you son and nothing is as bad as it seems. Love you forever, that will never change. Mom and Dad.” The 26-year-old Christy has been on the lam through five states and Canada since June 6, when he failed to appear in Schuylkill County Court on an assault charge against him. When he allegedly threatened President Donald Trump online, federal marshals and the FBI got involved in the chase. The reward for Christy has risen to $20,000 for providing information that would lead to his arrest. The bounty was $5,000 in August. He is considered armed and dangerous due to the threats he made online, and the weapons police believe he possesses. He stands 5 feet, 10 inches tall with blond hair and green eyes and weighs about 157 pounds. Robert Clark, a supervisor with the U.S. Marshals Service’s Fugitive Task Force, said the reward for information leading to Christy’s apprehension will be paid in cash upon his arrest, not after trial. U.S. Marshals have established a tip line, 484-358-1974. Anyone who thinks they have may seen him or know his whereabouts is asked to call the tip line. Thursday night’s Facebook message also refers to Christy’s alleged theft of three handguns and ammunition from his uncle Gerry Debalko’s home along Klinger Road in Butler Twp. on July 25. Police were called to the home, but Christy managed to give them the slip. “Ask the cops why Uncle Gerry had a loaded Hi-Point mag at his house, but no carbine, and why he’s been hanging out at the local skydiving club,” the message says. Late on Aug. 24, Christy was recorded on a security camera during an alleged burglary of Skipper Dippers restaurant on Route 309 in Rush Twp. On Sept. 4, federal officials also believe he broke into Skitco Iron Works on Route 309, 1½ miles north of McAdoo. Christy is also wanted for making threats on social media against Northampton County District Attorney John Morganelli and police attempting his arrest. He’s also wanted for a probation violation in Northampton County. Once he is in custody, Christy will first answer any federal charges against him and face prosecution before he answers any state and local charges. Christy posted on his Facebook page early in June, referencing a bench warrant and saying he would use “full lethal force” on any law enforcement officer who attempts to detain him. On June 12, he threatened Morganelli, stating he would shoot him in the head, along with Trump. Marshals apprehended him after a brief struggle in February in Texas in relation to the arrest warrant in Northampton County. He was found with a black powder handgun, although he is not allowed to have a weapon. Christy pleaded guilty in April to making terroristic threats to a tax collection clerk in Bangor, Northampton County. In that case, he was sentenced to 12 months probation and ordered to attend anger management classes. In 2010, then-Gov. Sarah Palin of Alaska filed a restraining order against Christy, accusing him of sending her threats. Christy was sentenced to probation after pleading guilty to harassing Palin’s attorneys by telephone, and he served two years in federal prison for violating his probation. In September 2015, Christy pleaded guilty to two summary counts of harassment after police said he harassed a teacher and administrator at McCann School of Business in June 2015. He violated parole during that incident. In March 2017, he was arrested for swinging a roughly 4-foot-long stick at Stephan Holly, who was McAdoo’s mayor at the time, following an argument over snow removal.
