Maria Villa, 44, says her son went to Upland High School with terror suspect Miguel Santana and a few years back they used to hang out skateboarding and playing video games. That friendship quickly cooled two weeks ago when her son called Santana to catch up and was lectured about the glory of Islam, Villa said. Villa’s brother, Manuel Gomez, right, said that in recent months Santana has been hanging out with just three or four other guys, all of whom would go to prayer together.  (Irfan Khan / Los Angeles Times)

David Bowdich, special agent in charge of counter-terrorism in Los Angeles, said federal officials took the defendants’ plans extremely seriously, and expended extraordinary resources to track and stop them.  (Gina Ferazzi / Los Angeles Times)
