Police said the search did not yield any results. Doctor Taleka Patrick of Kalamazoo, Michigan, went missing December 5. Her car was found on Interstate 94 in Porter County, Indiana later that night.
The 30-year-old doctor failed to show up for work as a resident on December 6 in Michigan. Her car was found 100 miles away.
Police hope new online videos she appears to have shot herself will help find her. In the videos, Patrick calls someone "love" and "baby." Police want to know if that unidentified person may know something about the doctor's whereabouts.
Surveillance footage from the night she disappeared shows Patrick trying to check-in at the Radisson Hotel. Authorities say she was last seen boarding the hotel's shuttle bus that took her to her car, which was parked at the Borgess Medical Center where she worked in Kalamazoo, Mich.
Her abandoned car was found with a flat tire off hours later. Inside was a credit card, some cash and her driver's license.
Her bizarre disappearance has investigators in two states stumped after their all-out searches have turned up nothing.
The Patrick family is offering a $15,000 reward for any information leading to their daughter's safe return.
