Amid mounting concerns over the safety of students in public schools, another disturbing case of alleged sexual misconduct on the part of a school employee has come to light.

For Klein ISD, which is located in the Houston metro area, the accusation marks the fifth instance of a district employee purportedly engaging in sexual misconduct with a student this academic year.

Isidoro Guerrero, who up until recently worked as an agricultural science teacher at Klein Forest High School since 2019, became the center of controversy in April following allegations of sexual impropriety with at least one student, according to a statement by Klein ISD.

The allegations against Guerrero stem from his involvement in what the district has called a “non-sanctioned trip” with students off school premises, according to Click2Houston. Upon receiving a tip on April 23, the district and local police promptly confronted Guerrero, which resulted in the termination of his employment the following day.

Guerrero has reportedly denied the accusations.

“While these allegations are deeply troubling, we are unwavering in our commitment to ensuring the safety and well-being of every student entrusted to our care,” the district said, per Click2Houston. “Upon learning of Guerrero’s actions, our immediate priority was to remove him from the classroom and notify students and parents of his termination.”

Despite the gravity of the claims against him, Guerrero has not yet been subject to arrest, and his teaching certificate remains valid, according to state records reviewed by the Texas Scorecard.

Guerrero’s dismissal is another event in a troubling pattern of misconduct among Klein district educators, which has prompted renewed scrutiny and calls for accountability.

This incident comes less than a month after Klein ISD officials fired cosmetology teacher Kedria Grigsby for charges related to sex trafficking, as previously reported by The Dallas Express. The teacher was implicated with her son in a series of forced prostitution allegations, in which Grigsby and her son Roger Magee recruited children from Klein Cain High School.

Three other instances reportedly preceded Guerrero’s termination, including an incident in which an elementary school teacher allegedly touched a 7-year-old to “gratify sexual desire” and the arrests of two other Klein ISD educators on charges of possessing child pornography.

As covered extensively by DX, the past year has seen numerous misconduct scandals involving public school teachers and staffers, including some in Dallas ISD. Such accusations of misconduct have led to calls for more transparency in state authorities’ handling of such reports, as well as improved background check procedures during the hiring process.
