Harrisburg, Pa. (Reuters) - A search was under way on Monday for a Penn State University student discovered missing when his parents arrived for his graduation and found out he had dropped out the previous fall, police said.
The parents of Jon Steindorf, 23, were hiring a private detective to aid in the search, his mother, Joanne Steindorf, told Reuters.
Police in State College, Pennsylvania, opened a missing persons investigation after he vanished hours before the graduation ceremony on Friday night, said Lieutenant Keith Robb.
His roommate in a downtown State College apartment last saw Steindorf at 11:30 a.m. Friday, Robb said.
Detectives were studying forensic evidence they gathered at the apartment but had not yet concluded a crime took place, he said. Steindorf left his phone, wallet and credit cards at his apartment.
Steindorf's mother and father, a State College radiologist, had arrived to take him to his graduation ceremony, only to discover he was missing, she said. In the days that followed, the Steindorf parents learned their son had actually dropped out of school during the fall semester and was not scheduled to graduate Friday night.
Penn State did not immediately respond to a Reuters request for comment.
Steindorf's mother said she last saw her son on May 4 and last spoke to him by telephone the day before he disappeared. He gave no indication that anything was amiss, she said.
Her son did not have mental health issues, as far as she knew, she said.
"He was a very good student,” she said. “He was in the [Penn State] Blue Band. He had a lot of friends. No one has any idea what has happened."
