It's been two weeks now since 30-year-old Teleka Patrick went missing. Police have no new leads on her whereabouts, but the Michigan woman's parents believe her disappearance is related to a mysterious phone call she received Dec. 4.

Patrick received the call the day before she disappeared when she was attending a lecture for her residency at WMU School of Medicine, Patrick's mother told MLive. School officials told Patrick's family that someone saw Patrick's body language changed after the call ended.

"...Her demeanor changed, she dropped her head in her hand. That's all they told us," Irene Patrick told MLive. 

Kalamazoo County Undersheriff Pali Matyas told MLive Wednesday they are aware of the suspicious phone call, but did not go into details

"The police are working and putting together the pieces for me," Irene Patrick told ABC News.

Teleka, originally from Queens, was last seen the night of Dec. 5. Police later found her car abandoned in a ditch on the side of a highway in Portage, Indiana. Reports originally said she was last seen in the parking lot of Borgess Medical Center where she was completing her residency. Her cell phone and purse were found inside the hospital.

But, according to surveillance footage released Thursday, Teleka is seen in the lobby of the Radisson Plaza Hotel & Suites around 7:30 p.m. Teleka was apparently trying to book a room, but was unable to. Her parents said she was unable to because she did not have enough money, MLive reported.

Matyas said Teleka left the hotel and was driven to the Borgess parking lot by a hotel courtesy van around 8 p.m., MLive reported. Her car was found two hours later with Teleka missing. There is now a $10,000 reward for information on where the missing woman is.

"We love her dearly and would like to have her making a contribution," the father, Mattahais Patrick, told MLive. "She's too prepared to just disappear like that into thin air."
