Jonthan Leroy Hepner, 56, of Erie, Pennsylvania, was last seen on December 24, 2017, after telling friends he planned to drive to Alabama to spend Christmas with his father. He never arrived, and concern grew when he did not return to Pennsylvania; his father requested a welfare check in January. Officers found Hepner’s apartment with a half-packed suitcase and his gun left on a nightstand, details that suggested his departure was unexpectedly interrupted.

The landlord reported Hepner had not paid January rent, described as out of character. Millcreek Township Police issued a nationwide welfare alert on February 19, 2018. A key development came when Hepner’s truck was found abandoned in Tennessee with his wallet inside but no sign of him. He was entered into the National Crime Information Center database as a missing person on July 12, 2018, and the investigation remains active.

What can readers add about Hepner’s movements in late December 2017 or anyone who might have seen his truck in Tennessee?
