A Franco-American man on a motorcycle journey across Latin America disappeared in late January in western Mexico's drug violence-plagued state of Michoacan, the French consulate said Monday.
Harry Devert, a 32-year-old New York resident, was last located in Zitacuaro, a western town near a reserve that serves as a nesting ground for monarch butterflies that migrate across North America.
According to US and Mexican media, Devert sent a final text message to his girlfriend in New York on January 25 before disappearing.
In his message, Devert wrote that the army had escorted him out of an area because "it was too dangerous for me to be" there.
His family says that his bank account has not shown any movements since then and that his cellphone has been deactivated.
The government has deployed almost 10,000 troops and federal police to Michoacan to restore security amid a year-long struggle between vigilante militias and the Knights Templar drug cartel.
Devert, who was writing a blog titled "A New Yorker Travels," planned to ride his motorcycle to Brazil for the World Cup and then head to Ushuaia, in Argentina's Tierra del Fuego region at southern tip of South America.
