The search is on for a missing college student who vanished just before graduation.

The parents of 23-year-old Jon Steindorf thought their son was graduating from Penn State University Friday. When they went to pick him up at his apartment, he was gone.

His parents have since learned that Steindorf disenrolled from his classes and wasn’t going to graduate. A statement from his parents reads:

Thank you for all of your prayers and concern for Jon. And thank you to everyone who is out searching for him and sharing the message of Jon’s disappearance. Jon had been enrolled as a Penn State student and our understanding was that he had completed classes and we were anticipating him to graduate this weekend. The most recent information we have is that he was not, in fact, still enrolled, and was not on the list to graduate. That does not matter to us. We love Jon dearly and want him to return safely to his family and friends. If anyone has seen Jon, or has any idea of his whereabouts, please contact me or the State College police department. Jon, if you are out there, we love you. Please come home.

Police say the missing student left home without identification, credit cards, keys or his phone.

Steindorf is 5-foot-10, about 170 pounds, and has brown hair and blue eyes. Anyone with information on his whereabouts is urged to call State College Police at 814-234-7150.

Authorities are investigating several possible sightings.
