Reports indicate that there was a major shootout before dawn on Monday between members of the military and members of the Matamoros faction of the Gulf Cartel. It is being said that "El Fily" was killed, though he is being listed as "Ciclòn 40". However, it does appear that this individual is one in the same as "El Fili", also known as "Ciclón 385", that I have posted about previously.
His name was Filiberto Munguía Bravo. They have changed a lot of claves apparently so he switched from 385 to 40 as you say.
Thought I'd also share that Dr Balaceras or Gerardo Silva, an associate of Fili and possible a financer, was said to have been killed in April 2016. I don't think that has been reported before. There is a corrido out about it.
Good questions that I was thinking about myself but, unfortunately, do not have an answer to. A while back ago there was a rumor that "Snr Cortez" was actually an alias of Alfredo "El Contador" Cardenas. I was, and still am, very skeptical of this as the emergence of "Snr Cortez" in Matamoros aligns quite well with rumors that "Cortez" of Los Metros fleeing to Matamoros.
I think the rumor about Sr Cortez and Alfredo C is without merit. Sources within Ciclones claim it was planted by the government. Unfortunately I don't have a picture of the guy, but of course his gun and that should be as good as a passport in the cartel world
