Overview
- Federal security leaders convened an emergency session as Mexico’s security chief said the mayor had a 14‑member National Guard detail and the gunman exploited the public event to carry out the attack.
 - Officials said one assailant was killed at the scene and two suspects were detained, with investigators seizing a 9mm handgun and seven casings and keeping organized crime as an open line of inquiry.
 - Mexico signaled it would accept international collaboration after a U.S. official offered deeper cooperation, and authorities said the weapon used is linked to past clashes between criminal groups in Michoacán.
 - Hundreds mourned Carlos Manzo at a public cortege, the governor was booed at the funeral, and demonstrators forced their way into the Michoacán government palace demanding justice.
 - In Hermosillo, at least 23 people died and 12 were injured in a Waldo’s store explosion that state prosecutors described as accidental as they investigate a possible internal transformer failure; separately in Ayacucho, Peru, a church cornice collapse killed Martha Pillaca Janampa and left her infant in intensive care.
