The search warrant affidavit gives a deeper glimpse into the case and potential evidence of the alleged sex crime that landed special education teacher Kelly Williams in jail.
Specifically, the affidavit suggests that Kelly knew that he was caught and tried to get rid of evidence.
Mansfield police say it's possible that 62-year-old Williams, who, up until his arrest last week was a special ed. teacher at Mary Orr Intermediate School in Mansfield, has video and pictures that incriminate him in sex crimes against children.
The search warrant affidavit lists computers, hard drives and DVDs among the items they were looking for at his apartment.
Williams worked for the district for five years. He was arrested last Monday after police say he sexually assaulted a student at Mary Orr in the boys' bathroom.
According to the search warrant affidavit, a female witness walked in on it.
"The witness stated the suspect looked up at her as she called his name...the witness then ran from the restroom seeking help," the affidavit says.
Investigators say Williams was supposed to report to the personnel office, but according to the affidavit, "The suspect rather than go directly to the MISD personnel office as instructed, went to his residence and removed the hard drives from his home computers."
Detectives assume that this was to cover up the alleged crime, or even others.
According to the affidavit, the detective "asked Williams if he had gone home and removed his hard drive and memory from his laptop so he wouldn't get caught and Williams replied, ‘Yea.'"
Williams is charged with the alleged assault and also improper relationship with a student.
He has since bonded out of the Tarrant County jail.
Mansfield ISD police are looking into whether Williams may have had inappropriate relationships with any other students.
Williams is out of jail after posting $300,000 bond.
