A woman was found dead Wednesday in the Southeast Washington home of a private security officer who had fatally shot himself a day earlier on the roof of a General Services Administration building, according to law enforcement officials investigating the cases.

D.C. police were called about 10:30 a.m. Wednesday to investigate a report of an unconscious woman in a single-family home in the 2200 block of Retta Gilliam Court, said Officer Araz Alali, a police spokesman. Police found the woman’s body but were not sure what caused her death and are awaiting an autopsy, he said.

The house, in the gated Fairlawn Estates community east of Anacostia, is the home of the man who killed himself Tuesday, according to two law enforcement officials, who were not authorized to discuss the cases publicly.

The man, a contract worker for the Federal Protective Service, which provides security at federal buildings, died of an apparent self-inflicted gunshot wound, a GSA spokesman said Tuesday.

Police did not release the name of either person and have not confirmed that the deaths are related.

A GSA spokesman said Tuesday that the security officer worked at the GSA building in the 1800 block of F Street NW. The officer was found with the gunshot wound and was taken to a hospital, where he was pronounced dead.
