MEXICO CITY — The sun wasn't yet up in Culiacan when David Téllez and his family began making their way to the city's airport for a return flight to Mexico after their vacation. But not long after they set out they encountered the first crude roadblock, an abandoned vehicle obstructing their way.
Téllez turned to social media to find out what was going on and saw that Sinaloa's state capital, a stronghold of the cartel by the same name, was filled with roadblocks and gunfire.
