Once Alvarez had learned that she got engaged to Fierro, prosecutors said he began plotting Fierro’s murder. He had Googled “how to kill your ex’s fiance,” and also did internet searches for “hiring hitmen,” “how to kill someone with a handgun” and “how to delete Google search history.”

Alvarez’s defense claimed that the shooting had been done in self-defense. Alvarez testified, per the outlets. He claimed that he had gone up to introduce himself to Fierro that day, and that the teacher had gotten aggressive and tried to kill him. He claimed that he tried to get Fierro to calm down before pulling out a gun.
