Sergio Martin, 50, was found dead in his Dinuba, California, home on November 6, 2023, at about 3:00 AM. He had suffered multiple gunshot wounds; a neighbor had requested a welfare check that brought authorities to the scene. Martin taught Spanish at El Monte Middle School in Orosi and was described as a well-regarded member of the community.

On April 24, 2024, authorities arrested a 16-year-old male juvenile and charged him with murder, burglary, and firearm offenses; because he was under 18 at the time of the incident, he cannot be tried as an adult under California law. Two adults were arrested on April 26, 2024: 21-year-old Jorge Arrieta and 20-year-old Joseph Garcia. Both face felony second-degree burglary and felony accessory after the fact charges, and Arrieta also faces a misdemeanor receiving stolen property charge. Arrieta remained in custody while Garcia posted bail.

The killing of a beloved local educator left the community shaken. If anyone knew Sergio Martin, his routines, or has information about the case, please come forward to help investigators.
