School officials previously told News 2 the little girl wandered out of the building at a time she and her 19 classmates were walking out to the playground.
"The child felt it was time to go home. She just got up her stuff and went to the door she normally would exit the building from," explained Murfreesboro City School's administrator Gary Anderson, adding, "The little girl was being watched, she was in the room with her teacher. And the rest of the children had gone outside."
In response to the incident, school maintenance workers reviewed the security measures to find ways to prevent similar incidents in the future.
"We feel confident the school is secure," said Anderson. "With all of the things that have happened recently in the country, our focus has been primarily preventing people from coming into the building rather than people leave the building."
Anderson told News 2 preventing someone from leaving the school building is a challenge because doors cannot be locked from the inside in the event of a fire or other dangerous situations.
Throughout the preschool, and others in the Murfreesboro school system, video cameras are in place. At Bellwood-Bowdoin other safety measures are also in place.
"As far as how she left at that time, I think that's best left up to us to work through to have our procedures in place to make sure this never happens again," Anderson said.
The child's teacher will meet with a school human resource officer to review the details of the incident and evaluate whether any procedural changes should be in place.
