Sources familiar with the investigation said USC received at least five complaints about Carrera this year alone. But they said the university did not open an investigation into Carrera until after The Times published a July story revealing drug use by former Keck Dean Carmen Puliafito. After that story ran, the sources said, some employees lodged another complaint against Carrera, and the university launched an investigation in August.
