The recent killing of a woman in Mexico is being investigated as a femicide, a gender-based crime under the country's law.
Video footage appeared to show a man entering a salon, inquiring about a woman named Valeria, and then handing her a gift before allegedly shooting her in the chest and head.
The victim, Valeria Márquez, collapsed on camera before another person ended the livestream.
The city's top official stated that the killing was linked to Francisco, who allegedly threatened Márquez multiple times after their relationship ended.
Francisco is believed to be the son of a prominent organized crime figure and allegedly ordered the femicide.
The suspect, identified as Ramón Ángel's son, had a romantic relationship with Márquez and had threatened her on several occasions.
The authorities have arrested 31 people in connection with the killing of Uruapan Mayor Carlos Manzo, who was shot during Day of the Dead celebrations.
Manzo had been an outspoken critic of organized crime and worked to root out corruption within the local police force.
Another man accused of participating in Márquez's killing has been arrested and is being held at the Altiplano maximum-security prison.
The Treasury Department has identified the CJNG as one of the most powerful cartels in the world and has imposed sanctions on more than 50 individuals and entities linked to the organization.
