The United States has announced a $10 million reward for information leading to the capture of two brothers believed to lead the Sinaloa cartel's operations in Tijuana. The reward targets Alejandro and José Luis Valencia, who authorities say have taken over the organization's lucrative border smuggling routes after the arrest of previous leadership.

The bounty represents a significant escalation in the U.S. government's efforts to dismantle cartel operations along the Mexico-California border. The Valencia brothers are accused of overseeing multi-ton cocaine and methamphetamine shipments through Tijuana's extensive tunnel networks and hidden compartments in commercial vehicles. Their organization has been linked to violent turf battles with rival groups competing for control of trafficking corridors.

This reward offer comes amid growing concerns about cartel violence spilling across the border and the flow of fentanyl into U.S. markets. The Sinaloa cartel's Tijuana faction has expanded its operations in recent years, capitalizing on border infrastructure vulnerabilities and sophisticated smuggling techniques. Law enforcement officials believe the brothers have maintained strong ties to the cartel's leadership in Sinaloa state while building independent power bases in Baja California.
