SAN DIEGO (AP) – A former elementary school substitute teacher in San Diego County has been sentenced to seven years in prison for receiving child pornography.

The Union-Tribune reports that 36-year-old Alejandro Castillo Jr. was sentenced on Monday.

Castillo pleaded guilty in September to receiving child pornography and acknowledged he collected images of children as young as 6 involved in sex acts with adults.

He was assigned to a sixth-grade class at Los Altos Elementary School in the Chula Vista Elementary School District when he was arrested.

Castillo previously worked at youth camps and schools.
