Police identified the suspect as Ronald Lee Syvrud, 66, from the city of Benson. The former president said he had been unaware that a manhunt for the suspect was underway during his campaign stop at the U.S.-Mexico border wall.

Carol Capas, spokeswoman for the Cochise County Sheriff's Office, told The Epoch Times that the alleged threats were made on social media. Capas did not say whether police found any evidence that the suspect intended to make good on the alleged threats.

Syvrud was charged with two counts of threatening in connection with the posts about Trump, the sheriff's office said in a Facebook post. He also faces a felony warrant from Graham County, Arizona, for failure to register as a sex offender. He remained in the Cochise County Jail awaiting court action during the evening of Aug. 22.

Earlier that day, about four hours before Trump's scheduled border visit, the sheriff's office posted on its Facebook page a notice seeking the public's help to find Syvrud because he was wanted for other warrants and "as an investigative lead for threats to kill a presidential candidate."

The agency later updated that Facebook post, stating that someone alerted the sheriff's office about "a threatening message on social media...directed at candidate Donald Trump" on Aug. 21.

"This message contained language that indicated bodily harm to the candidate," the agency said, adding that investigators found a second Trump-threatening post from Syvrud on Aug. 22.

"As part of the operations plan in place for the visit of candidate Donald Trump...locating this subject was a priority," the sheriff's office Facebook post said.
