Security Alert JHMI: The security office at the Medical Institutions has received several complaints about a woman who solicits money and transportation from people on the street after identifying herself as a Hopkins employee. In each incident, the woman--described as a black female in her late 40s and of medium height and build--told victims she was having car trouble and needed a ride or money to get home. The woman, who has used the names Beverly Thomas, Denise Shaw and Marguerite Davis, gave a telephone number in Dean Michael E. John's office, so her victims could reach her the next day for repayment. Anyone having information about the suspect should contact Corporate Security Services Investigations, at (410) 955-9140.
