A welfare check on the morning of Friday, June 27, 2014, led to the discovery of 53-year-old Mary Anne Thomas unresponsive inside a Southwest Washington, D.C. home in the 1200 block of Howison Place SW. D.C. Fire and Emergency Medical Services responded about 4:15 a.m. and she was later taken to the Office of the Chief Medical Examiner, where an autopsy found a fatal gunshot wound. Her death was ruled a homicide.

The Metropolitan Police Department opened an investigation and lists her case among the major unsolved homicides for 2014. No arrests or suspects have been publicly identified, and the circumstances and motive remain unclear to the public.

If anyone has information about Mary Anne Thomas, her movements that night, or the neighborhood around Howison Place SW in June 2014, please share what you know with investigators.
