A Texas woman who worked as an elementary school teacher allegedly used an electronic dog whistle on one of her students in order to gain his compliance.

According to arrest documents obtained by KWTX, a local CBS affiliate, 46-year-old Amber Escamilla was arrested Tuesday and charged with injury to a child or disabled person. The documents stated that Escamilla was the teacher of a 6-year-old boy with autism and allegedly used an electronic dog whistle “when he got overstimulated.” According to the documents, the boy’s parents told police that their son wore earmuffs to school because he was highly sensitive to loud noises.

KWTX reported that Waco Independent School District police detectives were alerted to possible abuse of a student at Bell’s Hill Elementary School by Child Protective Services. The arrest documents stated that in November 2024, Escamilla reportedly “came into the break room and placed a device on the table, telling co-workers that she had this for when the victim ‘gets loud.””

The school’s principal told detectives that she confiscated an electronic dog whistle from Escamilla the same month.

When Escamilla was asked about the device, she reportedly told detectives that she only intended to use the dog whistle outdoors, and that she had only ever used it once at the school’s playground. She further told detectives, per the arrest documents, that “she would only exhibit the whistle to the victim as a threat to gain compliance.”
