Dallas police are searching for a University of Texas Arlington professor who's been missing for more than two weeks. Investigators are also searching for clues about Dr. Pablo Mora's disappearance.
UTA Psychology students are worried that their teacher could be in danger.
"He'd kind of become a mentor to us. It's pretty harsh. It's devastating," said UTA Psychology major Ruby Garcia. Garcia headed to class Tuesday morning, knowing that Mora wouldn't be there.
No one has seen or heard from the 41-year-old since he left his Dallas home on Avondale Avenue on Sunday, September 30.
His colleagues knew something was wrong when the assistant professor of psychology didn't show up for work and didn't return their calls.
"It's really suspicious I think. It makes you think something bad happened or something else is going on," said Psychology minor Lindsey Juarez.
Police say Mora's gray Honda Civic was found more than an hour north of Dallas at Ray Roberts State Park in Pilot Point. It's an area surrounded by 20 miles of some heavily wooded trails and a lake.
"I thought it was terrible, and I think the fact they found his car 50 miles away, it's sad," said Garcia.
Dallas police are leading the investigation, since Mora was last seen in the city.
The native from Chile has worked at UTA since 2009. He's been researching postpartum depression in inner city women.
"I hope they find him. He was going to be one of my professors next semester to finish my degree," said UTA junior Kevin Parada.
"They don't have any leads right now I've heard of, doesn't look good," said UTA freshman Clayton Johnson.
Dallas police ask anyone with information about Mora to call the missing person squad.
