Trent Rhorer , the agency 's director , said the breach occurred when a former San Francisco employee e - mailed records to her personal computer , two attorneys and two union representatives . The former employee , who had been terminated for performance issues , was attempting to demonstrate that she had faced a disproportionately high caseload , Rhorer said . He noted that the records contained Medi - Cal beneficiaries ' names , Social Security numbers and other identifying information . According to Rhorer , the records were " extremely contained " and did not include sensitive medical or health benefit information .
