MANSFIELD — A Pennsylvania man accused of threatening President Donald Trump and several Pennsylvania law enforcement officials is the subject of an Ohio manhunt after authorities say he left a stolen truck on Interstate 71 near Mansfield on Sunday.

Shawn Christy, 26, drove the truck off the side of the interstate between Rts. 13 and 39 around 4:45 p.m. and fled from the vehicle, according to the Mansfield Post of the Ohio State Highway Patrol.

It is unclear why he left the vehicle there, a state highway patrol dispatcher said.

The truck was reported stolen from the Skitco Iron Works in Hazle Township, Pennsylvania, which Christy is suspected of burglarizing, the dispatcher said.

Christy is considered armed and dangerous, and Mansfield area residents were asked to stay inside and lock their doors Sunday night.

Troopers were joined in the search for Christy by Mansfield police, Richland County sheriff’s deputies and U.S. Marshals. Anyone believing to have seen Christy in Ohio is asked to call 911.

Madison Local Schools in Richland County were closed Monday because district officials did not want children standing at bus stops or walking to school with a dangerous criminal on the loose, district Superintendent Shelley Hilderbrand announced on Twitter. Lucas Local Schools are also closed on Monday, the Mansfield News Journal reported.

Christy, of McAdoo, Pennsylvania, is wanted by the FBI, the United States Secret Service and the U.S. Marshals Service. He also has several outstanding warrants for burglary, a probation violation and failing to appear in a hearing to face an aggravated assault charge, according to the U.S. Marshals.

According to the FBI, Christy posted threats on Facebook in June, saying that he was going to shoot Trump in the head and use "lethal force" on any law enforcement officer attempting to detain him.

Authorities said Christy also made threats to shoot a district attorney in Pennsylvania and a police chief.

"Keep it up Morganelli," Christy wrote on Facebook, referring to Northampton County District Attorney John Morganelli, according to the U.S. Marshals. "I'll put a bullet in your head as soon as I put one in the head of President Donald J. Trump."

An arrest warrant was issued for Christy on June 19. Authorities believe Christy has stolen several vehicles in the past three months during his time as a fugitive, and they said he stole a truck near his hometown in eastern Pennsylvania early Sunday, which was the vehicle that crashed on I-71 near Mansfield.

Federal authorities are offering up to $20,000 for information leading to Christy’s arrest. He’s described as a white male, 5-foot-10-inches tall, weighing approximately 160 pounds. He has short hair and a beard, and he has a tattoo of a cross on his right upper arm, authorities said.
