In possible conjuction with a multiple shooting in southern Monterrey, several armed suspects conducted a massive campaign of blocking roads by gunpoint Sunday evening, say Mexican press reports.
The killings took place at about 1830 hrs in the Fomerrey 45 district where three men were shot to death by armed suspects riding in a two vehicle convoy.
Gangs blocked several roads in the immediate area of the murders forcing drivers of commercial vehicles as well as personal sedans to abandon them by gunpoint, and then using the vehicles to block roads.
The first blocks in or near the Formerrey 45 district included Avenida Garza Sada and calles Salto del Agua, Lazaro Cardenas, Alfonso Reyes and Diagonal.
Additional blocks were made on Felix U. Gomez where it crosses calles Constitucion, Calzada Madero, Colon, Conchello, Magnolia and Ruiz Cortines.
City state and federal forces are often combined in Monterrey to deal with gang and drug related violence into rapid reaction groups to deal with the major crimes and the blocks,however, gangs have been learning to coordinate blocks in conjunction with specific actions in order to frustrate police responses.
Officials have released that a total of 22 blocks were made in the city, but local press say a total of 39 blocks were made in the city, but by 2330 hrs only half had been unblocked.
