According to the New York Times, the killing of a 12-year-old Houston girl found last week in a shallow water of a city drainage ditch after having been strangled was already a horrific crime. It doesn't get any worse, said the city's mayor, John Whitmer. Then investigators arrested two recent Venezuelan migrants and charged them with killing the girl.
