Dr. Teleka Patrick, 30, began her residency at Western Michigan University school of medicine in Kalamazoo during the summer, the Kalamazoo Gazette reported. She vanished after attending a lecture at Borgess Medical School on Dec. 5.
Patrick's parents, Mattahais and Irene, say there are a number of questions about that evening. Their daughter apparently got a phone call during the lecture and other attendees said "her whole demeanor changed."
Patrick also tried to get a room at the Radisson hotel in Kalamazoo but did not have enough money. Her parents do not know why she would have rented a room when she had an apartment 5 minutes away from the medical school.
A state trooper found Patrick's gold 1997 Lexus in a ditch off Interstate 94 just after 10 p.m. Other drivers have reported seeing a car matching the Lexus's description driving erratically on the interstate.
Kalamazoo County Undersheriff Pali Matyas said the car was undamaged except for a flat tire. Investigators do not know if Patrick was driving it.
Matyas said a courtesy van from the hotel dropped Patrick at her car at about 7:30 p.m. Investigators do not know what happened next.
"We have nothing that points to endangered," he said. "We have nothing that points to voluntarily missing."
