A fresh development has emerged in the search for a missing Chicago Public Schools teacher. On Thursday, her family revealed new video footage showing her leaving her vehicle without returning.

Linda Brown, aged 53, vanished over the weekend. Her husband reported that she was already gone when he woke up on Saturday morning.

The family believes there is a possibility that Brown is traveling on foot, and they urge the public to remain vigilant in looking for her.

Although the family announced on Wednesday that her car had been located, Brown herself is still missing.

Chicago police have yet to release significant details about the investigation, and the family has chosen not to disclose the car’s location.

Her family spent Monday retracing the Bridgeport teacher’s last steps and calling area hospitals, but have turned up nothing. Now, they are pleading with the public to help them bring her home safely.

“We don’t know where she is. We need to find her because I’m breaking down and I don’t know what to do,” her husband Antwon Brown said.

Chicago police said Brown was last seen in the 4500-block of South Martin Luther King Drive, not far from where she lives, on Saturday. But flyers with Brown’s photo are now being circulated online and throughout the Chicago area.

The special education teacher at Chicago Public Schools’ Robert Healy Elementary School was set to return to work on Monday. Healy’s principal sent out a letter alerting the school’s community with a plea to contact police with any information.

The school offered students mental health support.

CPD asked anyone with information to call Area One SVU detectives at 312-747-8380.
