Jesús Navarro Montes

Mexican federal police announced the arrest of Jesús Navarro Montes, 22, in Sonora state in connection with the killing of Agent Aguilar.
He was being held in Mexicali on Mexican charges of human smuggling.
Acting on Mexican President Felipe Calderón's vow to hit the cartels hard, heavily armed federal agents on Tuesday encircled police stations in Juárez, Nuevo Laredo and Matamoros to relieve police officers of duty, disarm them and search for evidence that may link them to drug traffickers.
A day earlier, Mexican federal authorities announced the capture of Alfredo Beltrán Leyva in Culiacán. He is purportedly a major operator in the Sinaloa cartel.
Border law enforcement officers, while watchful of the rising violence on the Mexican side, say that so far it hasn't shifted directly onto the U.S. side.
"All the sheriffs along the border are extremely concerned about the escalation in violence in Mexico," said Don Reay, executive director of the Texas Border Sheriff's Coalition. "Anytime we see the violence increase as it has recently, the more worried we get that will cross directly onto our side."
The violence that broke out in the streets of Reynosa and Rio Bravo, Mexico, hasn't spread across the border to Hidalgo County, Sheriff Guadalupe Trevino Jr. said.
Border Patrol officials held a closed-door briefing for Rio Grande Valley law enforcement officers Thursday on the outbreak of violence just across the river.
"We tell our guys to be careful out there, to make sure we know where they are and to make sure they have backup on calls to the river," Sheriff Trevino said.
