A 15-year-old pleaded for his life as investigators say an elaborate plot lured him to his death

In the hours leading up to Miles Young’s death, the 15-year-old thought he was just going to meet up with a girl. Instead, authorities say, he was ambushed in a complex scheme and killed while he pleaded for his life. The killing has become a political flashpoint for supporters of tougher immigration enforcement due to the status of one of the suspects.
