Members of a Mexican army special forces unit fatally shot a high-ranking aide to the country's most-wanted drug dealer in a gunfight in the northern state of Durango, officials said Monday.
Luis Alberto Cabrera Sarabia was responsible for the operations of Guzman's Sinaloa Cartel in Durango and part of the neighboring state of Chihuahua, army spokesman Gen. Ricardo Trevilla said.
The army says Sarabia is know as "The Architect," and was named to the role after the December arrest of his brother Felipe Cabrera Sarabia, or "The Engineer."
Sinaloa gunmen traded fire with troops during the operation to arrest Luis Cabrera Sarabia on Friday. One of the gunmen was slain and 11 others were captured. Four soldiers were hurt in the gunfight.
Mexican officials said that another high-ranking member of the Sinaloa cartel, Fidel Mancinas Franco, was arrested in the northern state of Sonora on Saturday. Mancinas had been extorting money from immigrants seeking to travel to the United States, they said. Mancinas is wanted in the U.S. in connection with the deaths of 11 migrants during a car crash in Texas in 2009, officials said.
