CIUDAD VICTORIA, Mexico (AP) — A road trip to Mexico for cosmetic surgery veered violently off course when four Americans were caught in a drug cartel shootout, leaving two dead and two held captive for days in a remote region of the Gulf coast before they were rescued from a wood shack, officials said Tuesday.
