New York Times article.....US State Dept warning

I have not been to Zihua/Troncones in several years, but have always had a safe and delightful visit. This mornings' New York Times has an article about the shooting of a father, 14 year old son, and an uncle in Durango state. The state of Guerrero is on the US State Department's Do Not Travel list. I think this has been the case during past times that I've visited. Can someone address the current safety and risks of violence relative to the past? I'm planning to be there in a month or so....I'll spend a couple of nights in Zihua, then head up to Troncones. Thanks, in advance!

Days after two mass murder terrorist events in the USA, I know I feel MUCH safer here in Mexico. It's a tragedy about the U.S. citizens of Mexican descent who were shot and killed, but apparently they weren't warned by locals to stay off a particular road after dark, from what I've heard of the incident, owing to ongoing cartel/gang wars in their area. Simply a matter of wrong place-wrong time. We have no ongoing open wars among cartels or gangs here in Zihuatanejo. But we do have an army and a navy base along with hundreds of elements of the Guardia Nacional and state police. Their presence is much appreciated by folks who've lived here a while.
