Valentin Lavin, mayor of Temoac in Morelos state near Mexico City, was fatally shot inside the town hall on July 22 by two armed men who then fled on a motorcycle [1, 2, 3, 4, 5, 6]. Lavin had survived a previous assassination attempt at a petrol station near Temoac on January 31, where he was wounded but survived [1, 2, 3, 4, 5, 6].

Lavin was aligned with the left-wing Morena party led by President Claudia Sheinbaum, who took office in October 2024 [1, 2, 3, 4, 5, 6]. Since Sheinbaum's administration began, 14 mayors have been murdered in Mexico, including three so far in 2026 [1, 2, 6]. Nearly 100 mayors have been killed in Mexico since 2006 amid rising drug-related violence linked to military actions targeting organized crime [1, 2, 3, 4, 5, 6].

Lavin faced allegations of ties to local criminal groups. His mother-in-law and former municipal treasurer was arrested in 2024 and 2025 for involvement with the Los Aparicio gang and kidnappings [1, 2]. Authorities in Morelos have launched investigations and operations aimed at arresting those responsible for Lavin’s killing. The Morelos prosecutor's office said it would "exhaust all lines of investigation" [1].

Mexico’s federal government is carrying out Operation Swarm targeting corruption and crime networks linked to municipal officials, with 85 officials arrested across three states [1]. Official data show homicide rates have fallen roughly by half since last year, a decline President Sheinbaum attributed to her security policies, stating to Chinese media that the homicide reduction "is a result of security policy since she took office" [2].

High-profile local politician killings have continued, including Carlos Manzo, mayor of Uruapan in Michoacán, who was assassinated during Day of the Dead celebrations in November 2025 [2, 3, 4, 5].

Investigations into Lavin’s murder remain active, with Morelos authorities pursuing those responsible amid ongoing violence. The latest killing follows a pattern of attacks on local officials in the region.

The case remains under investigation as authorities continue their operations to bring the suspects to justice [1, 2, 4, 5, 6].
