TX Teacher Arrested on Felony Charge Involving Student

Rebecca Ontiveros, 25, a teacher at Marfa ISD, was arrested last Thursday at 1 p.m. on campus. She faces a charge of improper relationship between an educator and student—a second-degree felony carrying a sentence of 2 to 20 years in prison. Ontiveros was booked into the Presidio County Jail and released the following day on a $75,000 bond, according to Big Bend Sentinel.

Anonymous Complaint Sparks Investigation

A source with knowledge of the case revealed that the investigation began after the district received an anonymous complaint. The complaint reportedly included the initials of the alleged offender, which matched Ontiveros. Texas Rangers then interviewed both Ontiveros and the high school student involved to gather evidence. The details of those interviews remain sealed.

Accused Teacher's Car Impounded by Texas Rangers

Witnesses at the school described seeing Texas Rangers impound Ontiveros’s car during her arrest. The vehicle was sealed to preserve potential evidence, according to the source. Malcolm White, the Texas Ranger leading the investigation, declined to comment, citing the ongoing nature of the case.

School District Addresses Community Concerns After Teacher's Arrest

On Thursday evening at 8:21 p.m., Marfa ISD issued a statement to parents confirming the arrest of an employee earlier that day. The district emphasized its cooperation with law enforcement and its commitment to student safety, but provided no further details.

Public Records Sought for Sexual Abuse Case Details

The Big Bend Sentinel has submitted a public records request to the Texas Rangers for probable cause affidavits and warrants related to the arrest. These documents may shed more light on the investigation’s findings.

Ongoing Investigation Leaves Questions Unanswered

As the case develops, many in the Marfa community are left searching for clarity. The safety of students remains a focal point as law enforcement continues its inquiry into this serious matter.

Legal Options for Students Involved in Teacher Misconduct Cases

When allegations of teacher misconduct arise, students and their families are often left grappling with confusion and uncertainty about the next steps. In an interview with Texas sexual abuse attorney Anjali Nigam, we explore the legal pathways available to victims, addressing both criminal accountability and civil remedies for those impacted by such acts.

Editor Darla Medina: When allegations like this surface, what legal options are available for students or families who may have been impacted?

Attorney Anjali Nigam: When a teacher is accused of such misconduct, victims have both criminal and civil pathways available. The criminal justice system focuses on holding the perpetrator accountable through prosecution. On the civil side, victims and their families can file lawsuits against the individual and potentially the school district, especially if negligence—such as ignoring warning signs—played a role.

Medina: Does the school district bear responsibility in these cases?

Nigam: It depends on the circumstances. If the district failed to conduct proper background checks, ignored complaints, or didn’t enforce policies to protect students, they could face liability. Victims can seek damages for emotional distress, therapy costs, and other losses resulting from the abuse.

Medina: For families who may feel overwhelmed, what should their first step be?

Nigam: It’s important to speak with an experienced attorney as soon as possible. They can help navigate the legal process, preserve evidence, and ensure the victim’s voice is heard. Families should also connect with support resources to help the victim through recovery.
