According to officials from the Fillmore Unified School District, they received a report of possible wrongdoing by an employee at Fillmore High School and a student at the same school. From there, the district shared the information with police, who launched an investigation into the teacher’s aide.

Negrete is accused of sending inappropriate messages to the student, which investigators say were “improper and had sexual overtures” to them.

The communications were allegedly frequent and annoyed the student who received them. Negrete allegedly sent the messages via Snapchat and delivered them throughout the day and night during the period referenced in police reports.

In a separate incident involving a different student, police allege Negrete provided a marijuana cartridge in exchange for money.

Available updates did not provide additional information about either of the alleged incidents.
