According to a recent U.S. State Department report 92 Americans have been killed in Mexico from June 2009 through June 2010. Even though the David Michael Hartley shooting on Falcon Lake has garnered worldwide attention most other cases do not. Some homicides are of Mexican-American citizens visiting family back in Mexico and traveling to unsafe areas.
The State Department that monitors and advises on travel for U.S. citizens has issued numerous travel advisories to different parts of Mexico as a result of the drug-cartel violence. Most recently it issued a warning on September 10th asking Americans to avoid traveling to Michoacán, Tamaulipas, parts of Chihuahua, Sinaloa, Durango and Coahuila.
One of the many helpful travel tips the State Department offers is to make sure travelers carry U.S. consulate phone numbers with them and to register with the U.S. consulate in the Mexican city they are traveling to.
