Fred Preston has always prayed for protection, not for himself, but for his 16 year-old deeply disabled daughter Michelle.
He trusted the educators of Caney Creek High School to teach and nurture, but what's happened to his little girl on the campus has left him feeling profoundly betrayed.
"It about brought me to tears when I found out what they were doing to her," said Preston.
Because of her disability, Michelle sometimes exhibits problematic behaviors, like kicking and spitting.
FOX 26 News has learned that on multiple occasions at Caney Creek, Michelle's body and head were slammed against a wall and pinned for several minutes at a time by a veteran special ed teacher.
Because she's incapable of crying out, it wasn't Michelle who told her father, but rather a trio of eyewitnesses - a teacher's aide, a former aide and a fellow student. All say they are speaking out to head off more negligence and unjustified suffering.
"She pinned her up and pushed her head against that wall. That's abuse. You are not supposed to do that," said Sade West, a former special education aide at Caney Creek.
"She shouldn't be treated like that. That's a way nobody should be treated," said classmate and witness Bill Sholars.
"I was appalled," said Vicky Gollnisch, who still works as a teacher's aide at the high school. "I was actually disgusted with myself for being employed somewhere that would allow a teacher to mistreat a student."
FOX 26 News has obtained unimpeachable proof that the classroom aides reported the mistreatment to Caney Creek administrators.
So far, no punitive action has been taken against the teacher. She remains in the classroom.
Special needs advocate Louis Geigerman has examined the evidence.
"They need to do an investigation of child abuse in this case," said Geigerman.
Michelle's father is demanding immediate termination and criminal prosecution of the professional educator who three witnesses insist maliciously hurt his child.
"They need to get rid of her. They need to put people in there who care about these kids," said Preston.
A spokesperson for Conroe ISD confirmed an investigation is underway.
