Gaurav Gopalan, 35, was found unconscious and later pronounced dead in the 2600 block of 11th Street NW in Columbia Heights, Washington, D.C., in the early morning hours of September 10, 2011. He was initially unidentified for three days because he was found without ID and wearing women’s clothing and makeup. The Office of the Chief Medical Examiner ruled his death a homicide, listing a subarachnoid hemorrhage from blunt-impact head trauma as the cause.

Investigators reported that Gopalan had more than $130 cash on him, but his credit card and driver’s license were missing. His gold-silver 2007 BMW 328i was also missing at first and later recovered; police sought anyone who might have seen the car being driven that weekend and obtained surveillance footage of someone who appeared to be Gopalan walking along U Street the night of the incident. Gopalan was a Ph.D. graduate and Assistant Research Scientist in aerospace engineering and an active director and stage manager with the Washington Shakespeare Company. No arrests or public identifications of suspects have been announced; the case remains unsolved.

If anyone saw Gopalan, his car, or activity on U Street that weekend, can you share what you remember?
