By ADOLFO FLORES AND RICHARD WINTON August 19, 2014 For days, authorities say, two South Pasadena High School students plotted a massacre for when classes resumed after summer. They swapped ideas over Skype about using explosives and firearms to target three school staff members and kill as many students as they could, never realizing that their communications were being monitored by local law enforcement, according to police.
