Thirteen suspected members of Mexico’s Jalisco Nueva Generacion drug cartel were arrested in connection with the kidnapping and murder of an employee of the Jalisco state Attorney General’s Office, a military commander said Wednesday.

The cartel members were involved in “kidnappings, drug sales and murders” in the Los Altos region of Jalisco, a state in western Mexico, 15th Military Zone commander Gen. Gilberto Hernandez Abreu said in a press conference in Guadalajara.
