Marshals assisted the Mexican Marines in the 8 January mission, and pursued the extradition of Guzmán to the United States.

On 8 January 2016, Mexican naval forces moved into position to raid a house in Los Mochis, Sinaloa, believed to be occupied by one of Guzmán's top assassins or sicarios.

As they entered the building, an "intense" gun battle erupted between the marines and several armed assailants, leaving five of the cartel gunmen dead and six wounded.

During the chaos of the firefight, the marines discovered Guzmán, who fled the house through a series of tunnels and then attempted to escape in a stolen vehicle.

A statewide alert was issued for the stolen vehicle, and the Federal Police located and intercepted it about 20 kilometres (12 mi) south of Los Mochis near the town of Juan José Ríos.
