A former Westfield High School substitute teacher who allegedly sent nude photos of herself to a male student has been charged with online solicitation of a minor.

Tiffany Michelle Amos, 25, of Houston, told police investigators with the Spring Independent School District that she knew the boy was only 16 years old when she sent him the photos from her cellphone, court records state. She had his birth date – March 30, 1995 – in her phone, according to records.

On the student’s 17th birthday and a few times after that, the two had sexual intercourse at her Houston apartment, records state.

In a statement Thursday, Spring school officials said Amos was terminated as soon as administrators discovered the inappropriate relationship between her and the student. The termination date was May 2, but Amos was not allowed to substitute after the allegation was received April 24, a district spokeswoman said.

An investigation showed only one student was involved, according to the statement.

“The safety of our students is of the highest importance,” the statement said. “The criminal history and references of job applicants, including those who apply to serve as substitutes, are routinely checked before they are hired. The district takes every allegation seriously and, with the Spring ISD police department, will always conduct a thorough investigation.”
