MADERA - A Madera man was arrested at a local Madera elementary school regarding a child pornography complaint. The Madera County Sheriff’s Office Investigations Division received two CyberTips from the National Center for Missing & Exploited Children regarding the suspected possession of Child Sexual Abuse Material (CSAM) occurring in Madera County.

During the investigation, detectives identified 34-year-old Joshua Lee Hefner as the suspect in the case. Hefner is employed by Madera Unified School District and was assigned to Dixieland Elementary School as a part-time cafeteria and playground assistant at the time of the investigation.

On May 18, 2026, detectives with the Madera County Sheriff’s Office, working in coordination with the Central California Internet Crimes Against Children (ICAC) Task Force and Homeland Security Investigations (HSI), executed a search warrant at a residence in the area of Avenue 18 ½ and Road 19 in Madera.

During the search, investigators located electronic devices belonging to Hefner that contained CSAM. Detectives contacted Hefner at Dixieland Elementary School, where he was taken into custody.
