WHO:

CBS News - Rosa Alejandra Vargas, Uruapan’s welfare secretary, was arrested on suspicion of concealing a crime; prosecutors said she is related to people arrested in the murder investigation.

CBS News - Michoacán state prosecutor Israel Vega said Vargas had failed to appear when summoned by investigators.

CBS News - Prosecutors said the Jalisco New Generation Cartel (CJNG) ordered the attack. Authorities have arrested 34 people in connection with Manzo’s killing.

CBS News - Miguel Meza, a researcher at Narcopoliticos, said cartel killings can silence local leaders who threaten or interfere with cartel profits.

Yahoo - Quiroz is escorted around the clock by 60 federally appointed bodyguards. She said, “No one can fill his void,” and expressed worry about what would happen to her children if something happened to her.

Yahoo - Prosecutors said detainees include seven of Manzo’s bodyguards, government members accused of leaking his movements, and Manzo’s godson, accused of helping plan the assassination.

Yahoo - Manzo’s brother, Juan Manzo, accused Quiroz of covering for people responsible for the murder; Quiroz denied the accusations and said her family was “betrayed” by people close to them.

Yahoo - David Vázquez, a store owner, said extortion by local mafias had increased since Manzo’s death and his family temporarily closed its business.
