"It was kind of like a superwoman power thing. I can't believe it did that!" said Sandra Ferguson, who works at Sutter Elementary School in Antioch.
Ferguson noticed an 11-year-old girl in the front seat of a vehicle with an unknown man, and recognized her as a student at Sutter Elementary School.
Ferguson said the young girl looked scared. She sensed something looked wrong.
"I said, 'Sweetheart, is that your dad?' She said, 'No he's a friend.' I said, 'No, he's not your friend!'" explained Ferguson. "I put my car in front of his and blocked him in. I told her, 'You get out of that truck right now!'"
Ferguson then called the police, who arrested 51-year-old Santiago Salazar on suspicion of kidnapping. Salazar did not attempt to run.
The young girl was not hurt.
"Thankfully she was a guardian angel, preventing something terrible from happening," school principal Debra Harrington said of Ferguson.
Investigators determined that while the girl had been walking to school she was lured over to a vehicle by Salazar, a resident of Brentwood.
Salazar allegedly grabbed the girl by the wrist and pulled her into the vehicle.
