In addition to the East Baltimore Medical Center, Dr. Levy also reportedly treated patients at the outpatient center on Caroline Street, which is also part of the Hopkins system.

The problems only surfaced three weeks ago when a co-worker noticed something suspicious and alerted security. Levy killed himself in the early stages of the investigation, leaving behind many unanswered questions: what was the motive? Was anyone else involved? Were the images distributed online?

“Some people are wondering whether there are other boundary violations that occurred during the course of these `examinations,’” said lawyer Jonathan Schochor.

Several lawsuits have already been filed.

Police warn the investigation could take months.

Hopkins has refused interview requests.

Levy reportedly left a suicide note apologizing to his wife. He worked for Johns Hopkins for more than 20 years.
