Americans often travel to Mexico for low-cost medical services.
But bargain hunting in health care can be risky.
Over the weekend, according to relatives, four Americans were kidnapped in Matamoros, Tamaulipas, after traveling by car to the Mexican border city to undergo cosmetic surgery (tummy tucks).
Two of them were killed, while two survived the ordeal.
Border towns like Matamoros are among the most dangerous in Mexico.
