The special focuses on the story of Alfred Jimenez, a Northside Independent School District instructional aide who was known to students and staff as “Mr. Fred.”

Investigators said Jimenez died in 2024 after a student with intellectual disabilities pushed him and caused a fatal head injury.

Jimenez’s death sparked questions from his widow, colleagues and other educators about how the incident happened and called for changes to how schools protect their staff.
