A graphic by the San Diego County district attorney's office, displayed at a news conference along with evidence seized in the investigation, shows how an alleged drug dealer used cellphone text messaging to communicate with his "faithful customers." Seventy-five San Diego State students, including many business or criminal justice majors, and 21 nonstudents were arrested. The 19-year-old alleged ringleader had been praised in a university publication as a model student.
