The witness got the license number and the child's father chased the suspect in his own car. "I've seen that car in this neighborhood before a number of times watching people," said eyewitness Deborah Lyle.
Pedro Ramirez caught up with the kidnapper at a park and yanked his daughter out of the car.
Police said the kidnapper took off and Ramirez chased him down again.
Police said eyewitnesses helped police find the kidnapper hiding under a truck, just around the corner from the park.
