Alexander Mazin, 27, was shot and killed on February 25, 2018, outside a 24 Hour Fitness in San Diego’s Midway District as he was leaving the gym. The attacker was identified as 46-year-old Ernesto Castellanos Martinez, who had previously dated the woman Mazin was seeing. The confrontation escalated and Martinez shot Mazin multiple times, killing him at the scene.

Reports say jealousy and unresolved issues from Martinez’s past relationship with the woman motivated the attack. Martinez had allegedly assaulted her several weeks earlier and reportedly called her the day of the shooting, threatening to kill Mazin in front of her. After the killing Martinez fled to Mexico and authorities pursued him there.

Mazin’s family described the deep grief left by his death and the permanent void it created. If anyone knew Alexander or has information about the events around February 25, 2018, please share what you know.
