"Not even a minute later I hear my car backing up in the driveway," Castro said.
Castro said she didn't think and she started running after it. She caught the thief at the light, yanked open her door and yelled at him to give it back.
She said that is when the thief took off again, dragging Castro while she held the door until she fell off. The man got away but Castro wasn't done. She went to Facebook and asked people to be on the lookout.
"My uncle, a few hours later, called me and says, 'I just spotted your car,'" Castro said.
They found it parked with no one inside near 31st and Wells Street and took it back. She also found two cell phones in it.
"We started going through the phone. We removed the SIM card and put it on a different phone," Castro said.
She found selfies of a guy pointing a gun at the camera along with a jacket and marijuana in the car, all of which she turned over to police.
"My message to him is, do better," Castro said. "At the end of the day, you lose because I got my car back. You gonna learn today."
