In a terrifying San Diego case, 33-year-old Jesse Alvarez was convicted of killing Mario Fierro, the fiancé of his former girlfriend.
The shocking revelation came to light when prosecutors presented evidence of Alvarez’s online searches, where he had sought information on how to kill your ex’s fiancé and questioned California’s laws regarding shooting someone attempting robbery.
Alvarez’s Fatal Confrontation
Alvarez’s motive stemmed from the discovery, via a Facebook post, that Fierro was engaged to his ex-girlfriend, Amy Gembara, whom he had dated on and off between 2015 and 2019.
According to FOX 10, Alvarez’s anger escalated to a point where he meticulously staked out Fierro’s North Park home for over an hour before fatally shooting him six times, including four shots to the head, following a heated altercation.
The prosecution further revealed that Alvarez had taken shooting lessons after learning of Gembara’s engagement, emphasizing the premeditated nature of the crime.
Both Fierro and Gembara were teachers at Cathedral Catholic High School in San Diego, where Alvarez had unsuccessfully attempted to secure a job, seemingly driven by an obsession with his ex-girlfriend.

San Diego Prosecution Planned
Gembara’s efforts to obtain a restraining order against Alvarez, who relentlessly attempted to contact and track her down, were denied after he promised to cease contact. However, within two days of making that promise, Alvarez resumed his attempts to reach Gembara.
Alvarez entered the testimony during his San Diego trial on March 7, arguing that his passion and his comprehension that Gembara had broken up were caused by untreated autism. In an effort to minimize their importance, he wrote off the internet searches as bad fantasies.
In a surprising twist, defense attorneys argued that Alvarez did not intend to kill Fierro during the confrontation, asserting that Fierro had initiated the violence, forcing Alvarez to act in self-defense.
Nevertheless, prosecutors and the convicting jurors were unconvinced, underscoring the severity of the crime and the premeditated nature of Alvarez’s actions.
